I have tried How do I receive incoming Google Voice calls using Empathy? and How do I set up SIP voice calling in Empathy?, but nothing works on 13.04.
I don't want to store my login information on another site, so this solution is out.
How can I accept incoming Google Voice phone calls with an Ubuntu app on 13.04? I'm currently using Empathy but will gladly use anything that prevents having to use a browser.
