Sip in general with an ATA can seem conflict using two devices behind NAT. You cannot choose port forwarding -- and that is a good idea when the option is there.
My service allows 3 real world IPs. If I tried iCH with an ATA and Vonage, I would have problems unless I used a hub and let the ATA get its own IP.
Later I experimented with a second Router, and experimented with running with both routers using NAT but linking them for local IP interaction -- that was problematic. (I also got the second router to experiment with wireless -- USR8022)
My final answer was to email Vonage and ask to switch the ATA to 8062/8063. I left my iCH ATA using 5060/5061, and never seriously cared about a soft phone. The USR8022 I am using without NAT, my RP614 is my NAT to the real world and is my DHCP server. It had keyword blocking and such that cuts down many annoying pop-ups.
The important thing to consider is that if you are trying to run the SAME account in two places at once, you cannot specify alternate ports, and you likely will have side-effects. You really need to do without one device, or get a second account. With a second account, does P8 allow different ports? Or does it traverse NAT more competently?
On the flip side P8 allows multiple DTA310s to ring the same number. Some people do that here. VoicePulse also, I believe, allows that with an ATA. My best guess is that they send the same initiation to more than one registered phones. That would also seem like someone could fake another connection and piggyback on your account -- however they likely authenticate the MAC address, and could also ensure one device per by assigning each known phone a different port assignment.

In the eStara context, what does "registering" mean? And what "server" is it referring to exactly? Before I uninstall this masterpiece, I thought I'd at least try to understand that and maybe see why it won't. |

I tried estara behind an ADSL modem/router. Kept getting the message "registration rejected" "server could not be reached, or it did not respond".
I tried just about every setting, with & without the DTA connected, no luck. Then I tried disconnecting the DSL line and made a dial up connection to get a "real" ip address and it worked fine. Quality wasnt too bad either, not great, but if you were on a trip somewhere without broadband it would do for a quick call.
The problem must be with the way the software deals with NAT etc. Beyond the scope of my knowledge I guess but if anyone has any ideas I would be grateful. |

That crossed my mind, but then I figured that all the people above who said they did get it to work couldn't possibly not be using NAT. And what use would this product be with that huge limitation? Can one of those people say either way? |

Well, I am able to make a call now but receive one way audio. I believe the problem is related to the fact that I need to use 5061 for SIP and 8001 for RTP. I am probably using the wrong outbound proxy...if packet8 even has one or supports it.
Just thought I would share. |

It's not surprising that softphones won't work with Packet8 behind NAT, even when they use STUN. If you'll recall from the Packet8 tech presentation somebody posted (»systems.stanford.edu/projects/andrews.ppt), they don't use standard STUN/TURN for NAT traversal. It's a proprietary protocol they created because TURN wasn't ready yet when they were developing the system (see slide 23). So, while this will work if you have a "real" IP, it won't work behind normal NAT. Now, if you poke holes in the NAT for the appropriate ports, it might work. Anybody tried it?
(Incidentally, that "blacklisting" I was talking about earlier went away after a few hours; probably has more to do with the softphone leaving connections open when it crashes than PAcket8 not liking me anymore.) |

The Intertex IX66 router/firewall/nat does a superb job solving all these problems. It uses stateful packet inspection and will "fix" SIP messages. It also opens media ports dynamically. Works like a charm with multiple hard- and softphones, using multiple SIP accounts, highly recommended. |

Re: Got Softphone Working with Packet8
Well, I am not sure that is just a firewall issue. I took my laptop to work where I have a one-to-one nat mapping and still only got one way audio.
Possible I will have time tomorrow to watch the syslog for info on what packets might be dropped....
Has anyone successfully had xlite function with packet8? |

Minneapolis, MN | Yeah, X-Lite works great for outgoing calls for me (with a real IP and no NAT). No love at all for incoming calls, of course, though. |

Re: Check out the Intertex IX66!
Is the Intertex IX66 available in the US? It seems like a superb product. I wonder what it would take to get it to work with Packet8 and Vonage? |

Re: Got Softphone Working with Packet8
Warning! Using softphones is apparently frowned upon. I just got this after starting up my softphone:
===
Subject: Your IP will be blocked
From: tech-support@packet8.net
We're receiving SIP messages from a non-compliant Packet8 endpoint from
your IP, and as we have an obligation to the rest of our customers, we
cannot allow non-compliant endpoints to communicate with our proxy. This
email is serving as a warning before we actually block your IP. If we are
still receiving these SIP messages from your IP after an hour of sending
this email, we will block your IP for 24 hours.
Thank you,
Packet8 Operations. |

While I would tend to agree with their position (so far, no "bring your own SIP agent" feature was ever released  , it is for sure bad news
On the other hand, they could start to offer this, even at the same price, I'm sure some people would go for it.
Imagine the market for a PDA with GPRS and/or 802.11b doing "softphone" to P8 ? They do have an unfair advantage, they seem to have good voice quality with G.723, so it would fit just fine (I guess) in a 3 timeslot data call.. |

as i understand it, P8 is concerned with authenticating the user. They are worried that a softphone user would share his account or lose control of it. The multiple endpoint policy would put the account (and margins) at risk. |

Included in the SIP packets are the type of client you are using. Kind of like the way your web browser tells a web server the client type. |

I would expect by MAC address? Public IP? Can you use the same ports and IP address behind NAT and the DTA will work? I don't know but I gave my thoughts anyway.
Or, maybe I should have really read Automate 's answer an kept quiet?

Hope they consider giving the customer a choice:
1. Use only the DTA that Packet8 provides for as many residential minutes as you want.
or
2. Use more than one SIP client but only the first X number of minutes are included in the unlimited plan. Also, the customer would have to support themselves with any 3rd part SIP client.
If you choose the 2nd option it kind of eliminates someone from giving their password to their friends. |

The MAC address is not included in a normal SIP communications. Vonage uses the MAC address only to TFTP your specific configuration file. The config file includes your password. Once you have your config file, all SIP authorization uses your password not the MAC |
