A Hint of Things to Come for Google Voice VoIP?

There is an interesting article over at the Disruptive Telephony site, talking about how the author has gotten his Google Voice number to work entirely over IP, using something called a “SIP” address to initiate the voice session.  In an unofficial way, the author of the article is saying that VoIP calling is already possible with Google Voice.  (although his method has not worked for everyone who has tried)   Here is a quote from the article:

For some of us who have had Google Voice numbers for quite some time (mine dates back to the pre-Google-acquisition GrandCentral days), it’s always been a bit frustrating that the only way to call a GV number was through the good old PSTN. Particularly because the PSTN is so… well… limiting. When I’ve been building apps in Tropo or Voxeo’s Evolution platform, I’ve wanted to route them to my GV number… and I have to do this via the PSTN side. No big deal on one level, but it’s just inefficient. If the call is already all on the IP side, why not just keep it all IP!

It seems the author is knowledgeable about IP communications, and has used a client called Yate to use the Google Voice service in an IP state.  Make sure to read the article through a couple of times to understand the route the author is taking, and also please note that some people have had trouble with it.  Either way, it is a good sign that VoIP calling could be in our future with Google Voice, something that we have been hoping for, especially on our Android handsets.  I can picture the cow the carriers would have if it comes to fruition!


  • I’ve been using pbxes.org for months to use GV over SIP.

    I installed Sipdroid and it works perfectly. If others cant get it to work then they are failing horrible. I’m not even in the US 😀

  • I’ve been using Gizmo5 to do exactly this the entire time I’ve had GV, since July 2009. It’s also officially supported as one of the phone types you can configure in the GV settings; it was supported even before Google bought Gizmo5. Granted, I’ve had some issues along the way getting it working properly on Android, but right now it works great with the Sipdroid app and never had a problem with it on my PC.

    The best thing about using GV entirely over VoIP is the price: free! The only thing I pay for is $10 every 3 months for T-Mobile prepaid which I only use when I need to make or receive a call without wi-fi, which is very rare.

    It’s a shame that Google is terminating Gizmo5 service on April 3. They suggest using GV for Gmail, but that’s no replacement. GV for Gmail doesn’t receive calls most of the time, probably because I have Gmail open almost 24/7 and it times out or something. I hope they release their own VoIP client for PC and Android soon, but until then I’ll settle for one of the other SIP services. Sipdroid recommends PBXes (both from the same company) for use with GV, but it’s based in Germany so latency could be an issue.

    I am deleting my androidguys.com bookmark because of this article. Something called a SIP? Read the article through a couple of times? Should my mom find herself in need of regurgitated Android news, I’ll point her in your direction.

    Doesn’t android 2.3 & up have a built in voip setting, do you can just enter the sipdroid server & proxy info & you’r good to go! : (proxy01.sipphon.com) the four digit #’s are (6070) should already be there.and you’re password,that is assuming you signed up with gizmo5 when it was joint with Google.goodluck.
