Connecting to Google Voice Via SIP in VOIP Tech Chat

Re: Connecting to Google Voice Via SIP

caseydoug : At least we cleared up the mystery of whether GV has once again begun to alllow inbound SIP connections.

There is little standardization in the way call destinations are formatted. It takes a lot of trial and error, a lot of combinations and permutations, before you can conclude that GV is really not allowing these connections.

dyrewolfe : callwithus behaved exactly the same way (everything but the GV # was stripped away) even with "sip:" added. sipgate threw back an error "unknown domain" and setting up a dial string in sipsorcery resulted in a timeout.

wifi4milez : Using a dummy IP address still results in a connected call, so it must be discarding the @ipadress portion, and it also seems to not care that the string begins with "sip:". Very odd, especially how using "sip:" passes the call directly through the GV system (instead of terminating in the GV voicemail).

Re: Connecting to Google Voice Via SIP

Mon, 24 Aug 2009 18:20:05 EDT

caseydoug : I suspect it is some sort of odd manipulation that both Sipgate and VoicePulse are doing with the string. You were also going to try calling your number at a dummy SIP address. That might show whether it strips out the number of an address that won't otherwise connect.

Re: Connecting to Google Voice Via SIP

Mon, 24 Aug 2009 17:58:56 EDT

wifi4milez : Ok, this gets even stranger. I tried doing (gvnumber)@googleip and the call went through as before. Dialing via this method yields my GV voicemail if I dont answer the call. Upon checking the logs however, it shows that I connected to just (gvnumber) not a SIP address. I then decided to try the method by attaching the prefix "sip:" to (gvnumber)@googleIP and dialed away again. This time it also rang, however instead of being picked up by my GV voicemail the vm of my cellphone (part of the ring group) picked up the call. A check of the GV call logs shows a missed call from my Voicepulse account, but not a SIP call (I doubt if its even setup to display SIP calls). Finally, I tried it using Sipgate but also including the "sip:" prefix. My cellphone rang, but when I didnt answer it also skipped the GV voicemail and went directly to my cellphones vm box. A quick check of the Sipgate logs shows that even with the "sip:" prefix, the call is recorded simply as a regular number.

caseydoug : Another way to tell might be to look at your ATA logs. I'll be interested to see what you come up with.

It's purely academic at this point since, for me, the Sip Sorcery app does pretty much everything I was trying to do through a GV SIP connection.

I will check this evening. I can also try testing this by entering in (myGVnumber)@bogusIPaddress and see if it still completes the call. If it does, then we know its just grabbing the digits and completing it via the PSTN.

I just created some outbound forwarding rules (speed dials) on my VOIPo line, with destinations as follows:

myGVnumber@216.239.37.15:5061

and

sip:myGVnumber@216.239.37.15:5061

The first one worked, i.e., got to my GV voicemail, whereas the second one timed out. Call logs showed the outbound speed dial numbers, so there was no way to tell whether the first one was a SIP call. The only indication is that the speed dial entry itself shows only a number for the first one, but a SIP address for the second. Clearly, VOIPo is just grabbing the number on the first speed dial.

I will test it out in about an hour and report back.

No, mine was also originally GC. I can't say I've tried everything to make this work -- I haven't done any real troubleshooting. But when this was working before, it was pretty straightforward, and I didn't have a problem. Then it simply stopped working. I think I'm doing what I did before.

Strange. Have you tried originating from different phones and providers? Is it possible that, like dryewolfe, your provider is just taking the username of the SIP URI and sending it out as PSTN?

I have been able to dial into my GV number(s) via SIP using a softphone with both my Sipgate and Voicepulse accounts. I do not think the provider is just using the SIP URI and passing it through, however I am not sure how to verify that.

Thats exactly what I am saying. I am doing nothing other than dialing (myGVnumber)@googleIPaddress:5060. This works on both my GV accounts, long since converted from GC.

Nope. Any asterisk-1.4.x should work with the solution provided by nerdvittles, except when using Paul Marks GV Dialer Python scripts for AGI that requires asterisk-1.6.x that requires a new Bridge () function to make the outbound call transparent. If you want to use the Paul Marks GV Dialer Python scripts for AGI to place an outbound call, hang up, and wait for the incoming call, then you can use asterisk-1.4.x too.

So do we have an easy way to integrate GV (GC in this case) into Asterisk for outbound calls without dialing * or other keys to place calls?

If you take a look at the source code of GC Dialer add-on for Firefox (no longer there), it is written in a JavaScript (JS) language that can be easily modified to use as an AGI script, let alone converting to other (scripting) languages, for those who are fluent with a JS language. However, knowing GV will terminate GC by 9/12/2009, this effort may be a waste.

For those who want a hosted solution, check out the threads on Sip Sorcery, for example this one: »GV dial with sipsorcery.

Edit: I'm not sure how either would work with GC.

I checked out nerdvittles, and it seems in order to get his solution to work you need a special home grown version of asterisk (that is available for download on his site). I would do that in a flash, however that would mean reformatting my current server and losing all the configuration files. Also, I dont know if NV's version includes a GUI which is critical for me.

Interesting. I tried several numbers with IVR menus, and all worked. I wonder, however, if I were now to try calling GV from this phone to pick up voicemail, for example, whether I might have a problem. I'll give it a try later.

Re: Connecting to Google Voice Via SIP

Tue, 18 Aug 2009 15:56:41 EDT

caseydoug : That is pretty much what I do, with two exceptions. First, I do not register anything to G5 because of an incompatibility between G5 and my ATA having nothing to do with GV. Instead, I forward G5 to myusername@sipsorcery.com. That works fine.

Second, I adapted a dialplan from mxnerd (»mysipswitch.com/forum/viewtopic.php?p=8892) which supports seven, ten, and eleven digit dialing.

The one weakness I have found in this system is that DTMF is a bit spotty. Sometimes it works, sometimes it doesn't. I suspect this is a GV issue, since I don't think that either G5 or Sip Sorcery touch the audio. Any thoughts on this?

Edit: I was able to fix the DTMF issue (I think) by switching to Inband on my ATA. The setting is unavailable on the ATA's browser interface, and I had forgotten that it can be accessed via the ATA's command line interface. A little research and I found my own post from years ago that explained how to change this setting. Good thing I write things down in this forum!

emoci : As it stands (provided you do not have your own PBX and are not happy with a little software on your PC) your best bet is:

Incoming SIP:
-Get a 1-747 G5 Number
-Point your GV to your G5 number
-Register your G5 Number on your ATA/SoftPhone/Agregator Service)

Outgoing SIP:
-Get a SipSorcery acct.
-Use either the G5 number from above (this is ideal if you want to register to SIPSorcery and be done with it) or another G5 number.
-Create secondary extension in SIP Sorcery (eg. user-gv)
-Register G5 Number to SipSorcery (eg. in this case the contact field would be user-gv@sipsorcery.com )
-Add the following dialplan as the 'Outgoing Dial Plan' for the extension:

Then simply register an ATA into SipSorcery

That's assuming you want to keep a PC running 24/7. If you wouldn't be running the PC otherwise, the electricity costs alone will quickly eat up any savings.

The Sip Sorcery solution, discussed elsewhere, does not require installing or running anything on your computer. Even that, however, requires that you have an ATA and a broadband connection. And I certainly wouldn't count on it being around very long. "Free" seems to mean different things to different people.

jerryscuba : I think I found a way of using Google Voice to call the US for free.
One can open an account with a VOIP provider that offers Pay As You Go. One provider I know of is Future-Nine.
Then one can get a free US number from IPKall and link it with the SIP account. Then one can use this number in GV to get calls forward to.
Well an than there is this little inconvenient call button on GV. GV will call your US number and then the party you wish to call within the US for free.

I did not try exactly this solution as I have an official US number already. However, it worked with my current VOIP provider with my own US number.

Good luck!

Sure, I'll use them if there is no alternative: Google Voice is nice for free calling for example, but if somebody has something as good, and they usually do, then I will always choose it over whatever Google is pushing.

There are a dozen search engines that will do as good a job as Google's for anything I will need. I used ask.com for several years without a problem and am now giving Bing a try.

Thanks for this information. This means other SIP -> GV shall still work.

You could be right.

Isn't GV or Grandcentral using Asterisk, or anything similar? Why don't they just block the incoming Invite from proxy01.sipphone.com but go the long way to set up another proxy?

Hush ..., don't give them ideas. They probably didn't know this. ;)

lacklusterbb : caseydoug,

I simply followed the instructions on nerdvittles, using a hosted pbxes account not an asterisk server. I was already usng pbxes.com so I had a ring group set up and didn't need a new one. Following the instructions nerdvittles gives, you've got to set up an extension, trunk (again, you don't need to use 2 Gizmo accounts, I used an existing free digits account I had since they allow free SIP URI dialing in the account information for the trunk, and I plugged the dial plan in the instructions into the dial rules area of the trunk) and the outbound route. You point your ATA to pbxes.org to register it, using your SIP userid, which you'll see in the dial box under "Device Options" in extensions, and password.

I'd still like a more detailed explanation of what lacklusterbb did with pbxes. Which service was the trunk, which the extension, where did your ATA register, and how were outbound and inbound routes set up? Even if it doesn't work now, it might in the future.

caseydoug, emoci,

I use a free pbxes account. I just tried an outgoing call and it still works. This is different from the first set of instructions that nerd vittles gave out on general SIP dialing; it's based upon GV's integrated SIP dialing via Gizmo. Google would have to lock down SIP dialing with Gizmo, which I don't see them doing at this point--then GV would truly just be a virtual number service and not much different from many others (except for the fact that there aren't many charges right now while it's beta).

My interest is in the specifics of the setup at PBXes...since you can't exactly create a custom extension...

I did find out last night that you can use 'p' as a pause character and got up to a point...but not functional yet...

Any insight on how you set up at PBXes...

Caveat: FreeDigits is currently functioning only under its TalkDigits incarnation --- althought the SIP-URL is still freedigits.net. Nobody knows if the service will be viable in the near or distant future. With that said, another SIP-URI option is a free account with CallCentric. When forwarding to CC, the incoming CC SIP-URI should read 1777xxxxxxx@callcentric.com (using the CC assigned UserID) and the user selected CC password. The outgoing SIP-URI from the redirected provider must show 1777xxxxxxx@in.callcentric.com. (Note the placement of "in." in front of the CC domain.)

Re: Connecting to Google Voice Via SIP

lacklusterbb : No, it existed in Grand Central. It was the only way to get a Grand Central/GV number to ring an ATA directly without routing to an IPKALL or other DID affiliated with a VOIP service registered to the device. Google has retained the relationship with Gizmo; nerd vittles just gives instructions on using Gizmo's SIP URI dialing with GV. You don't need to use 2 Gizmo accounts. In setting up the G5-GV trunk, I used a free digits account in the account information since they allow free SIP URI dialing. You follow the nerd vittles instructions and plug the daling info into the trunk dialing rules. You have to set up an extension and inbound routing following the instructions given by nerd vittles.

I don't believe those instructions work any more. You can no longer make a direct call to the GV SIP address, although you can make a SIP call to G5 and have that forwarded via SIP to GV.

You should be able to do this with both pbxes and Asterisk. The advantage of Asterisk is that you can set up a dial plan to enter the "*, PIN, 2, #." You cannot do that with the free version of pbxes, although you may be able to do it with the paid version.

However, as lacklusterbb mentioned, GV has been pretty erratic of late, so it's probably not worth investing a lot of time until it settles down.

When I dial my Gizmo5 "forwarding" number directly and manually input the *, PIN, 2, phone number, #, everything works as expected with two way audio. Can anybody shed some light into this for me?

What little I know about Linux, I learned from playing with this machine. It uses a Fedora distribution, but I believe it is somewhat stripped down. The XO has no hard drive and only about a gig of NAND, but it has an SD card slot and can also use a USB flash drive. I can run simple single-file programs from the SD card or the USB flash drive, but I have not figured out how to install more complex programs to those drives, so most programs on the machine run from the internal NAND.

Yes, I agree, the subject was SIP>GV directly. (snip)I was testing various call-forwarding scenarios.
1)IPK/G5>GV (via G5 website): works/inconsistent
2)IPK/G5>GV (via X-Lite): works/inconsistent
3)MJ>GV (via X-Lite): works/consistent

Again, so that I understand what you are doing, only the third scenario is a direct SIP connection, right? There you are entering the GV IP address into your X-Lite while registered to your MJ account?

In the first two scenarios, you are entering your IPK number, which is PSTN, IPK forwards to G5, and G5 forwards to GV. Several of us have succeeded in getting G5 to forward to GV since Google shut down SIP access, but this is not what I meant by "direct" SIP>GV.

I also notice that I get a generic VM greeting when I access my GV number in this manner. Calls directly to my GV number continue to get my personalized VM greeting.

Yes, I noticed this also. You can get GV to "recognize" the number by adding a contact with the number you are calling from. Thus, if I add a contact called "Test Contact" with the same 11-digit number as the first part of my G5 number, GV will see it as a call from Test Contact, but not a call from my G5 number. In fact, if I create a personalized greeting for Test Contact, it will play that greeting when I call in (assuming the G5 CID is passed).

I'm not sure what you mean by PIN authentication (I'm out of town so can't test), but how are you accessing this address? Forwarding from Gizmo, or direct access from any SIP source? If it's forwarding from Gizmo, then several addresses have worked this way, albeit inconsistently. But if you could access GV via SIP without using Gizmo, that's news.

That's correct. Nevertheless, I already had this working before I posted my article.

What I haven't been able to figure out is whether Google closed that connection and then reopened it, or whether it was never closed. When we lost the SIP connection a couple of weeks ago, I tested it using a number of different proxies, but never tried forwarding from Gizmo until mazilo indicated it was working.

caseydoug : That's why I asked my question about whether this was EVER shut down for Gizmo. Look, it's always been a mystery to me why GC/GV allowed Gizmo as their only SIP connection outbound. Perhaps they've always had an inbound SIP connection as well, but nobody discovered it until recently. If that's the case, I could see them closing off all the other connections but leaving this one open for the few geeks that would play with it. I doubt that they are losing a lot of revenue from people who are doing this.

They work great with PBXes.com and also can place calls to US for about 1 cent/min so I use as a backup trunk for US calls. If you don't want the annual charge you can now get a free number for a specific phone# to call but you have to "activate" the number as if you own it by answering a call and input a 9 digit authentication code.

Thanks also for the tip about Call Hunting.

Earlier in this thread, Oroman posted about being able to avoid the *2PIN requirement by setting up a dummy contact and routing calls from that number to the (disabled) GV number. Have you been able to get that to work with Gizmo? It works fine from my PSTN numbers, but not from Gizmo, possibly because the Gizmo connection is forwarded rather than direct. If you try it, please let me know one way or the other.

I set up two free Gizmo5 accounts, one of which is forwarded to GV via SIP for outbound calling, and the other is set up as one of my GV primary numbers for inbound calling. Using a speed dial entry (or Mysipswitch or various other methods), I can dial the forwarding Gizmo number and make a call out using GV.

I understood this. Actually, you can do this with a single (not duo) Gizmo5 account + a GV account. Configure your Gizmo5 account with Call Hunting (If no answer on Gizmo5, ring elsewhere) feature and just call your own Gizmo5 number from your ATA configured to your Gizmo5 account. It will probably ring six times before the call gets forwarded to your GV line through SIP. Once on GV, press * and 2 to place outbound PSTN call.

One thing I haven't figured out, however, is how to call out without dialing extra digits. I'm using Mysipswitch, which has powerful dial plan scripting, but I don't see how to make it pass the *, 2, PIN, and phone number after the call has been forwarded to GV.

May be, this will help if you are using asterisk PBX system.

Re: Connecting to Google Voice Via SIP

caseydoug : I've been playing with this a bit more, and it looks like the ONLY way to connect to GV via SIP is by forwarding from Gizmo. I've tried to reach the GV URI directly while registered with several other providers, including Gizmo/Sipphone, and I can't connect. Forwarding from Gizmo seems to work most of the time, but not always.

I'm not familiar with the various dial plan scripts, but wouldn't this be pretty limiting? That is, if you need to dial Gizmo first (which then forwards to GV), is it possible to create a dial plan that sends "*-PIN-2-DestinationNumber" AFTER dialing Gizmo? If anybody knows how to do this using the Ruby script in MySipSwitch, or any other way, please post it.

I believe GV has already patched the hole to turn off this feature. Otherwise, can you imagine how much GV has to pay all SIP2PSTN calls.

Anyway, I tested this Gizmo5 (SIP) to my Google Voice and it worked. This only will benefit those who have PSTN numbers to forward incoming SIP calls to. For instance, you can configure all your SIP accounts to forward unanswered incoming calls to your celphone through GC/GV using this approach. So, you can be somewhere else to receive your incoming SIP calls through your cellphone and/or other PSTN phone.

dkmcknight : I use both Skype AND Google Voice.

Right now, I'm on a Skype Unlimited US & Canada subscription ($2.95/month, which is dirt cheap). Their Unlimited World plan is $9.95/month, which connects you to 36 countries (with some limitations on cell phone access in most countries).

I'm working with a partner in Australia, so bought a Melbourne DID through Skype ($30/year) -- so when he calls me on the Melbourne number it's forwarded to my GV number. No additional Skype cost for that call, since the inbound number terminates at a US number, which is included in my US/Canada subscription. He's going to do the same thing going the other direction, so I'll be able to call a US number, and it will ring to him in Melbourne.

I also have my GV and Skype numbers in my cell phone service calling plan so I can call to, or receive calls from, either number, and it doesn't count against my cell minutes. I'm pretty pleased with what I have.

Right now, though, neither service offers everything I need. Both, combined, get pretty close (for very little money).

I have an office number that's with another VoIP provider, that I would move in a New York minute to either Skype or GV -- but unfortunately neither allow number porting, yet.

The first provider that offers GV features, SIP, number portability and Skype pricing gets 100% of my business. I'll consolidate. In the meantime, I don't mind using them both.

Yes, it would be lovely if Google Voice became a more open SIP-compliant platform as the article hopes, but I don't think Google, or GrandCentral before it, made any mention of its internal architecture or opening that up -- they likely use SIP compliant equipment out of de facto convenience. I mean, if GrandCentral servers were SIP compliant all along and they were open to the idea of an open architecture, why did they even bother getting Gizmo involved?

Still, I hope he's right this time.

I believe GC will not allow its calls forwarded to another GC number. I don't know if Google has lifted this option off of a GV service. Anyone?

When I tried to in GC to forward to my own GC/GV number, I saw a warning that GC cannot be forwarded to other GC numbers, but I assumed it was refusing to forward to MY OWN GC number. Are you saying that GC could not be forwarded to ANY GC number? I guess this means that it would not let you define another GC number as a "ring to" number? And if that is the case, I suspect that GV would be the same.

I wonder whether all of these restrictions are in preparation for Google's introduction of a real VoIP service, or what else they have in mind. With no LNP and no SIP access (i.e., no real ability to give up my existing PSTN and VoIP services), I'm unlikely to make a lot of use of GV.

As celtec points out, if you have converted to GV, you can still reach your GC number via SIP using the IP address he lists. In fact, while I can no longer reach my GV number via SIP, SIP is the ONLY way I can reach GC, for example to leave a voice mail message. But there is not much I else I can do with GC: the settings tab is unavailable, so I can't add or change "ring to" numbers. When I call GC via SIP, the call forwards to the numbers selected in the last setting I had before converting to GV. The only other setting that sort of works is the "Quick Rule," which allows me to forward to voice mail, but I cannot forward to any other number (I think this is the case; I have been unable to test it fully).

If I had two GC accounts and converted only one of them, I believe I would have been able to reach GC via SIP, and then forward that call for free to my GV number. If someone still has a working GC account and a GV account, I'd be interested to know whether this can be done. (I still have an unused GC invite, but it won't allow me to create a new GC account.)

Yes. First, you need to make sure the phone (PSTN / VoIP / Cell) you will be using to call your own GV number must be listed on your GV contact list. Otherwise, you will need to let GV voicemail to intercept the call before you can press the * key for it to prompt you for your PIN numbers. Once you have correctly entered your PIN numbers, you can press 2 to place an outbound call.

To summerize, GV does not accept SIP address in phone settings. What Oroman did was, he entered a fake number 1234567890 in his GV phone list, checked it and set it to not ask for PIN. And in his ATA, he used a fake CID 1234567890 with the outbound proxy set to be the GV proxy. The whole thing has nothing to do with GV accepting SIP address in phone list. :D

You are right, and I apologize to Oroman for not reading his earlier post carefully enough. My ATA supports a second line, but requires that it use the same SIP proxy address and outbound proxy address for both lines. It is therefore difficult to create a "dummy" user id without losing use of the adapter for other providers. In fact I was trying to change the name on my pbxes user account so that I would have a numeric user id which GV would "recognize" (otherwise, it comes through as "unknown," which I believe I discussed earlier in this thread). I never got around to doing that.

But Oroman's trick is pretty interesting in another respect. He said he was able to dial his GV number by adding that GV IP address as an outbound proxy server address, and then just autodialing the GV number. In other words, he used a Gizmo SIP server, a Google IP address as an Outbound Proxy server, and then dialed his Google Voice number (was it the PSTN version, without the @, or was it just a 10 digit number?). That is very strange indeed, inasmuch as one shouldn't be able to use an outbound proxy server that way. For example, to make a SIP call to my Lingo phone, one would enter number@SipProxyServer, not number@OutboundProxyServer. Outbound proxy servers (border session controlers) help navigate the network; to my knowledge, they don't set up the call.

I'm not saying it can't be done; I just don't understand it. Oroman, since you say you autodialed your GV number, did it include the IP address as part of the number dialed, or was it just a 10 digit number? If the latter, is there any possibility that the call went out over PSTN via your Gizmo account?

Unfortunately, we may never get to test this because GV has shut down SIP access. It would be interesting to know just what that IP address was.

Caseydoug, did you define your SIP phone on the GV phone list?

I am not able to define a SIP phone (other than Gizmo) in the GV phone list (Settings/Phones). I have been out of town all week, so I can't really test this properly now, but when I did, it wouldn't let me save my SIP address, which begins with letters. I WAS able to save a SIP address beginning with numbers (e.g., Callcentric or Gizmo), but as I recall, the Callcentric number ended up ringing on a PSTN number I didn't recognize in the 206 area code (I think I discussed this earlier in this thread). Others apparently got different results (cbrain, for example), so maybe I entered the number improperly. I'll try it again when I get home.

I am still trying to figure out what GV does with various types of phone entry in both Contacts and Phones. It looked to me like entries in the form "number@domain.com" were being truncated so that only the number was dialed. On the other hand, when I tried to dial a SIP number in the form "name3-201@domain.com," GV told me it was charging 2 cents per minute, and then it commenced to ring (no one answered). Again, this will take more work, assuming GV will permit any SIP dialing at all.

I should have said ‘Then apply my fix by adding a dummy contact with the same number as your PSTN phone and route calls from that dummy contact to the disabled phone and no other phones in your list.’ You can route other contact phone calls to the disabled phone.

I think GV has a problem with a contact having the same number as one in the phone list. After I added the dummy contact and I was editing several contacts and GV would not allow me to put a check next to some contacts. Logging off and back on fixes this problem. This never happen before adding the dummy contact.

I even gave you the config of the second port on my ATA, but apparently I wasn’t clear enough. I believe the second port on my ATA is straight SIP. I did log on to GV with it and got the voice prompt without a PIN.

Mazilo, the second port on my ATA is not really a Gizmo account. I am not providing any Gizmo account information. I am using the Gizmo’s proxy server, but according to caseydoug I could have used any other free server.
SIP is the name I assigned to the phone. It was defined as HOME.
I was not routing any GV calls to the SIP phone. I defined it in the GV phone list to avoid having to enter a PIN. I disabled (unchecked) it to prevent GV from trying to route calls to it. A disabled phone equals PIN problem (nothing to do with SIP or PSTN) which requires the PIN FIX.

Caseydoug, did you define your SIP phone on the GV phone list? If it was defined did you disable it? Did you try to duplicate the PIN problem on a PSTN phone by disabling it? If not please try. Then apply my fix by adding a dummy contact with the same number as your PSTN phone and only route calls from that dummy contact to the disabled phone.

It is no trick to avoid entering the PIN when calling in from your Gizmo account provided you call the GV PSTN number.

If he was able to avoid the PIN when calling the GV SIP address, however, that would be significant.

caseydoug : cbrain, can you save a sip number with alpha characters, not necessarily dial out, but just save it?

Edit: I was wrong. I AM able to enter alpha characters. I'm not at home, so I can't be sure where the call is going. GV says the cost of the call is 2 cents per minute, which suggests that it is converting the alpha characters to numbers, and trying to make an international call.

oroman, if your sip number is your Gizmo number, then I think I understand what is happening. The real test is whether you can call in with a free sip account, with no cost for the call and no monthly charge. Is that what you are doing?

I'm in test mode on GV and only have two phones (PSTN and Gizmo) defined. I'm using GV to receive inbound calls on my Gizmo phone and make long distance calls on my PSTN phone. It is my understanding if a call comes in that is not defined as a contact it will ring all the phones that are enabled on the phone list. Enabled,I mean a check mark next to the phone# in the phone list. I did not want to receive calls from GV on my PSTN phone, but when I unchecked it GV required a PIN. I found the above solution on the GV forum.
Maybe you didn't define the SIP phone on GV. I'm using an ATA and I used 1234567890 as the SIP UserID. When the call came in to GV it had phone number 123-456-7890. I then defined 123-456-7890 in my GV phone list.

Now I'm confused. You are saying you can make GV calls out via SIP? I was not able to do that. SIP numbers with alpha characters before the "@" are not accepted as contact numbers. SIP numbers with all numeric characters before the "@" are accepted, but are essentially truncated, so they do not work. I can make inbound SIP calls to GV, but not outbound SIP calls from GV.

Yes, it worked on SIP without a PIN. I’m assuming you didn’t have the SIP phone enabled on your GV phone list. The same thing will happen on a PSTN number. Try it. Uncheck one of your PSTN phones and call GV with it. A PIN will be required. Adding a contact will the same phone number with calls routed to the unchecked PSTN phone will correct the problem.

PX Eliezer : "777" is what CallCentric uses, as you said. It is not a real POTS area code. Nevada tried to get 777 (think about it) but was denied.

-------------------------------------

However, an upcoming problem is "747" which is the Gizmo5/SIPphone code. Later this year 747 will also become a real POTS area code in California.

Mark my words, this will cause problems. But Gizmo5 is like the spaceship in the awful 1973 SF TV series "The Starlost"---the bridge crew has vanished and the ship is on autopilot.

BTW, "The Starlost" was a fine work by Harlan Ellison. The original screenplay was given a Writers Guild Award. But the actual TV series, produced in 1973-74, was so altered by the producers (and was SO bad) that Ellison had his name removed from the credits and replaced with the pseudonym "Cordwainer Bird".

The strangest thing happened when I then called my GV number with that callcentric number as the only active extension. It didn't ring the phone connected to callcentric. It did, however, lead me to a GRAND CENTRAL voicemail announcement (not GV). Finally, a few moments after I hung up I received a call from a woman who said I had been trying to call her. I didn't think to ask her what her number was, but Callcentral uses a 777 "area code," which I think does not exist.

I was a little embarrassed, and I don't want to experiment with using that number again. :)

Edit: I just checked my GC voicemail, and the message I left was not on it, so it went to someone else's voicemail. I also checked the CID of the woman who called me, and the number was nothing like the one my GV number was forwarded to. Go figure.

IP ending in .15 rings forward numbers that are "checked" in GV. Local voice mail picks up and is connected.

IP ending in .17 rings a number that is NOT checked in GV (i know becuase the number it is ringing is a DID on my asterisk box and see it in the logs).

IP ending in .18 rings the same non checked number that .17 did above.

IP ending in .19 rings the same non checked number that .17 did above.

IP ending in .20 does the same as .17 and .19 for me.

IP ending in .16 rings someplace (not sure if it one of my non checked numbers), and when nobody picks up my GV voice mail picks up.

IP ending in .11, .12, .13, and .14 rings the same as .15 above.

I cannot determine how to ring a certain non checked number. Only one of my non checked numbers rings (ip ending in .17 - .20)

IP ending in .10 is dead.

The CID number coming over to my asterisk box is 4065309999

I think I understand. But aren't your GC and GV numbers the same?

I have one that I upgraded to GV and one that is still GC...

Nonetheless it seems that having the right IP range makes a difference...(switching the xx from 15 to 19 fixes the VM presentment issue for me)

Good find indeed...

Anyone still wondering how this is beneficial: You can now have any third party DID from F9, CallCentric, or even international forward directly to GV via SIP URI (hence no cost)...from there GV will ring all your phones as usual

emoci : No I mean GC(not GV number)@IPAdress rings all my phones...but when it comes time for VM to take the call, GC VM doesn't answer...cell's VM (where GC is forwarding to) answers instead...

GV doesn't seem to have the same issue...

caseydoug : You mean if your cell phone is one of the GV "ring to" numbers, and you call CellNumber@216.238.37.xx, it reaches your cell phone? Funny, I tried that in the very beginning and it didn't work.

As for reaching voicemail quickly, it may be reading as busy.

emoci : One odd thing...this actually works with GC numbers as well...but when I call this way a GC (non-upgraded number) I end up in the VM of the phone to which that number is forwarding within a ring or two... (no press 1...but I don't know how it is triggering VM so early on the receiving phone either...)

Update:

SIP Calls to GV numbers: Ring all forward-to phones, receive GV voicemail if no answer

SIP Calls to GC numbers: Ring all forward-to phones, do not receive GC voicemail...the VM from one of the forward-to phones takes the call...

The SIP URI does not seem to get updated instantly if your Forward-To number changes...

caseydoug : Thanks, emoci. That's not quite what I had in mind, however. I am using an old Azacall adapter to receive GV forwarded calls and also to call out using a GV SIP connection. I previously had been using this adapter as a pbxes extension. I can do both simultaneously -- making a SIP call to GV does not use any of my pbxes trunks -- but GV does not recognize the number it sees when I use this adapter to call in if the adapter is configured for pbxes. Switching the adapter from pbxes to Gizmo or Callcentric solves this problem because both services use numeric user names. But if I do that, I'm not using pbxes.

It doesn't really matter too much, however, since there is not much benefit to GV recognizing the number. I still have to press "* PIN" to get to my voicemail and other services.

Are either of you pbxes users? I would like to be able to let this adapter register to pbxes again, while at the same time using it to call GV. But as a pbxes "extension," the adapter needs to have a name based on my pbxes user name. All pbxes extensions have a dash ("-") in them. Use of alpha characters in the phone number seems to prevent GV from recognizing the phone as a contact. If you happen to have an all-numeric pbxes user name, I'd be interested to know whether the dash alone causes this problem in GV. In other words, if you try to SIP-call your GV number from a pbses extension, how does GV treat the call?

Alternatively, I could terminate and recreate my pbxes account. However, I've heard horror stories about accounts getting blocked when someone tries to do that.

If you're assigning a user-number@pbxes.org to the above SIP URI and trying to call that form outside...it is one of those known issues with PBXes...not just in this scenario..
(solutiong is to create an inbound route with the user-number as the Trunk name...)

If you have trouble calling this SIP URI from PBXes that's a different story...I'll have to test

So far I simply added the SIP URI as a VoXalot Speed Dial...

What bothers me is that I've seen that IP when receiving calls from GC to MagicJack since last February but always assumed it was MJs servers... :uhh:

caseydoug : Ok, here's a little more information. I found the IP address by forwarding GV to my Gizmo number. When I called my GV number from my cell phone, the logs showed the call as MyCellNumber@IPAddress. I noticed that a couple of the via statements also used MyGizmoNumber@IPAddress (this is from memory, so details may be slightly off). Putting 2 and 2 together, I tried "dialing" MyGVNumber@IPAddress using a speed dial setting on my adapter, and it worked to get me in to my GV number.

For those who don't want to look this up themselves, IPAddress was 216.239.37.15:5061. Yours may be use a different server, however.

To this point, I have not been able to get in using a direct URI connection from my adapter or a soft phone. The logs show a connection, but then an immediate "BYE" from GV. So I'm guessing GV will accept connections only from SIP proxy servers. However, I have made this work using several free SIP proxy servers, including pbxes, Callcentric, and Gizmo. Pbxes requires that telephone extensions be named with a format that includes alpha characters, so GV does not recognize the telephone number and treats it as "unknown." Both Gizmo and Callcentric use numeric usernames, however, and these are recognized as 10-digit numeric telephone numbers which you can name and put in your contact list. When a call comes in from one of these numbers, and if it is in your contact list, the caller is announced just like any other caller. Interestingly, the Gizmo number looks identical to the number of the Gizmo "ring-to" phone, but is treated as a different phone. I don't believe you can use the "Call" button to call one of these SIP numbers.

It was quite easy to forward my Gizmo number to my adapter, and to set my adapter to register with Gizmo. I set GV to ring the phone connected to that adapter, and turned off call presentation and screening for the "contact" connected to the SIP number for that adapter. Using speed dial, I can call into my GV number, press "*2 PIN" while it is ringing, and then dial out to US numbers for free. The speed dial on my adapter is not flexible enough to include pauses and other characters, but I'm certain that this could be done using a more powerful adapter. And of course a dial plan using asterix could make the dialing process identical to using a normal telephone for outbound calls.

If Google allows these SIP connections to continue, I would seriously think about giving up other telephone services. Between its features and its free US calling, GV appears to be a pretty complete substitute.

dalrun : "What is the IP? Are you sure it is a Google IP"

I wonder if he's calling the Google IP address that sets up the call (I tried it w/ CC and got 'invalid #'). I haven't paid close attention, but it seems that all my incoming calls involve a single port 5060 packet from the provider and that the source IP is a constant.

caseydoug : mazilo, aren't you the Sultan of Cheap? :) I thought you would appreciate this. I'm right now working on a dial plan from my old Ling adapter.

celtic, I'd prefer not to publish the IP right now. It may not be the same for everybody, and in any event, I'd like to keep the usage low until I've checked out a couple of things. Suffice it to say it wasn't hard to find. I looked it up on whois, and it's definitely a Google IP address. It's not going through Gizmo because my adapter does not connect to Gizmo (although Gizmo forwards to my adapter).

Right now I'm working on spoofing my phone number so that I don't have to go through call presentation. If this is possible, there will constitute a potential big security hole.

Edit: I may be wrong about this being a direct connection. This adapter normally registers to pbxes in order to get dial tone. When I disabled the pbxes connection, I was not able to connect to the GV number. At the moment, I haven't determined whether reaching the GV number requires going through a SIP proxy. Even if it does, however, this is definitely a SIP to SIP (i.e., free) call.

In addition, I did set up the adapter to register to Gizmo. Interestingly, GV recognized the caller ID as my Gizmo number, but did not recognize it as the Gizmo phone that was already set up in GV. In other words, it is the same number, but it is treated as a GV contact, not as "me." When I turned off call presentation and screening for this "contact," the call went right through, and pressing "*" led me to my voicemail. Obviously, more tinkering is required.

What is the IP? Are you sure it is a Google IP or could it be Gizmo? I didn't think either Google Voice or GrandCentral directly communicate with your computer or adapter. Could you be going through Gizmo?

Interesting found. I believe you can configure asterisk with a dialplan context to dial out. :D

This is a direct connection, without going through Gizmo or any other SIP provider. From there I was able to get to my voicemail, press 2 to dial out, etc. There were a few hiccups because GV didn't recognize the "phone number" (so, for example, I had to enter my PIN to get to voicemail), but I suspect even this can be corrected.

What this means, of course, is that you can basically get totally free phone service using a telephone rather than a computer. I don't know whether the IP addresses will change or Google will otherwise block this method of making outbound calls. And for inbound calls, I pointed Gizmo directly to my adapter. I haven't found any way to forward inbound calls to my adapter without going through Gizmo.
