Re: Connecting to Google Voice Via SIP

Another question is WHY would they break them?

I can see no reason why they don't just allow SIP connections as an upfront policy.

I assume it would have something to do with paying for unlimited nationwide calling to the PSTN.

I'm quite serious really. If there's something I'm missing please let me know. For now the ability to do PSTN outbound calling is kinda sorta hidden; if it gets widespread and used by home PBXes I've got to think they'll curb it somehow?

Oh right I forgot there is a good reason they don't officially support SIP: you would then not visit the website where they can advertise to you.

Alternatively, after they get a large user base, they could begin charging a few dollars a month (or buy Vonage).

It seems that they disabled SIP access to GV. Calling to .13, .14, .15 addresses produces ICMP reply. While .16, .17 address es are still alive but route calls to GC not GV account.

I suspect they read these boards (and others).

Caseydoug asked:
“Are you saying there is a way to avoid the PIN when calling in via SIP? I know you can do it using a PSTN number, but I haven't found a way to call GV-SIP from some other SIP number without entering your PIN.”

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.
This is all irrelevant now that they cut us off unless you know another way to do it via SIP.

Mazilo asked:
'What exactly did you mean to have the SIP phone enabled on GV phone list? I don't see this option. Can you please elaborate?'

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.

For the moment, I can save a sip number for a contact and can click that number to successfully dial out.

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?

Caseydoug, I made a mistake in my previous post. I have 3 phones defined to GV (PSTN, Gizmo and SIP). I have an ATA with 2 ports, one defined for Gizmo the other for SIP. The SIP port is defined as follows:
SIP Server = proxy01.sipphone.com
Outbound proxy=216.239.37.15:5061
SIP Userid=1234567890
Offhook Autodial=(My GV#)
When I took the SIP phone offhook, it would connect to GV without PIN at no cost and I was able to dial out.
This stopped working this evening.
