Re: Connecting to Google Voice Via SIP

said by LHM :

Gizmo SIP connect to GV not working as of last night (5/8/09)? Confirm?
I tried it just now and the call was not connecting. I took a look of the SIP trace of the incoming GV->Gizmo call, and it looks like the trick is now officially dead. GV now does not use the offical Gizmo proxy (proxy01.sipphone.com) any more, instead, GV routes calls to proxy 198.65.166.147 (probably an internal proxy of Gizmo that was just set up to counteract this SIPping trick, remember the GV->Gizmo glitch on Thu or Fri?), and then the proxy 198.65.166.147 forwards calls to the official Gizmo proxy proxy01.sipphone.com. In another word, GV most probably has blocked traffic from proxy01.sipphone.com.

So, another party pooped. Enjoy it while it lasts!

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? I am no expert but someone may know the reason.

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

...remember the GV->Gizmo glitch on Thu or Fri?), and then the proxy 198.65.166.147 forwards calls to the official Gizmo proxy proxy01.sipphone.com. In another word, GV most probably has blocked traffic from proxy01.sipphone.com.
You could be right.

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

Was this a coincidence that Navid (a Gizmo5 Support) posted here (on Friday 5/8/2009) asking if anyone needs helps on G5 services?
