Call on mobile phones
There is an opportunity to call on mobile phones from gmail: https://support.google.com/chat/?hl=en&topic=30052&ctx=callphonehelp&rd=1. What should be done to implement this feature in your client? Thanks for great project!!
So if you're using google, I think google talk brokers the call if I recall for gmail.
Basically, you could check the invite that's sent out, but I'm pretty sure it's to a jid with the format([email protected]/srvres), but you can google that and see details as there are plenty of people doing it.
As well, google voice only supports, G.711 ulaw, which is barely compressed audio of 8000hz with a bitrate of 64 kbit/s per channel. This works fine on a normal connection, but I think is beyond what 3g can handle. In contrast, low end ISAC is 16000 and 15kbits/s more or less. More or less ulaw would need max of 64kbits/s down and 64kbits/s up to make the call.
As well, if you wanted to bridge xmpp to traditional sip you would need some sort of libjingle to sip gateway.
