Google Voice Applications
Adobe AIR Desktop Utility for Google Voice
Run it, log in your gv account and you can make call “connections”.
Google Voice in your mobile browser:
All these are to used to make calls through google voice easier.
When we make calls from google voice account, usually, we need something to receive the calls. GV makes the connection. However, google voice on mobile seems to be able to make calls directly.
With a computer only (when I don’t have a phone available), my favorite way to receive calls is using sip account. It could be anything like gizmo5, fwd, voipuser, voxalot etc. Set it up on a sip client like xlite/eyebeam, connect the account to ipkall. So when you make a call through google voice, GV->ipkall#->SIP(you pick up)->Callee#.

If you are ubuntu, linphone is highly recommended. Since empathy, xlite2.0 etc all gave me problems.
