![]() When that happens there will be more options to translate between SIP and XMPP with Google Talk/Voice. The Google Talk developer document does state they intend to implement the latest versions of Jingle and that would mean also supporting the latest version of ICE. Connect Zoiper to your PBX or voip provider and make crystal clear, echo free, voice or video calls through wireless and 3g. Feel free to contact us with support questions or for more information on whitelabel solutions. To work around the mismatch in STUN/ICE versions between softphones that do support ICE and Google Talk/Voice would mean proxying the media and that’s not something the sipsorcery service is geared for. Zoiper is an easy to use sip video softphone, with excellent voice quality and easy to setup. Unless something else crops up I think that’s pretty much the end of any attempt to integrate Google Voice XMPP calls with sipsorcery for a while. It also send the STUN binding request to initialise the media and as with the XLite it’s requests were rejected as malformed by the Google Talk/Voice XMPP server due to the newer STUN attributes. Rather flexible, this software lets you make voice and video calls. Zoiper is another leading softphone solution. Update: Thanks to Avi Marcus I tried out the Blink softphone which like the XLite also supports ICE. X-Lite is developed by Counterpath, as is the softphone software Bria Solo Free, which offers more advanced features. If anyone is aware of a SIP softphone that supports ICE please let me know. I tried out the free version of the Zoiper softphone as well but it doesn’t look like it support any version of ICE so I didn’t get anywhere with it either. The problem then became the Google Voice server not recognising the STUN request because it implements an earlier version of STUN/ICE and it doesn’t recognise the STUN attributes set by the XLite. Once that was fixed the XLite did send a STUN request as part of the media initialisation. ![]() Update: it was my own malformed SDP packet that stopped the XLite from working properly. ![]() The Google Voice server isn’t interested in RTP until it’s done the STUN binding request exchanges. Ideal for freelancers, small business owners or home users, the 3CX softphone allows you to make and receive calls. Once connected to your VoIP provider, it can be used to make and receive calls over your internet connection. The specific issue is they don’t send a STUN binding request on the RTP socket and instead launch straight into sending their own RTP stream. Look no further The 3CX softphone for Windows is a free app developed by 3CX, for use independent of the phone system. The problem is the counterpath softphones don’t seem to be implementing ICE properly or perhaps are implementing an earlier version. I’m not having much luck getting the counterpath softphones, either Bria 3 or XLite 4, to work with the Google Voice media server. ![]()
