I did find this thread and it did help me greatly.

But, (here's the but part)...

Now I cannot hear incoming calls.

My tablet rings, i can answer incoming, and speak and the people on the other end can hear me, but i cannot hear them.

This only happens with incoming calls. Outgoing calls work perfect.

So now with simonics SIP GV gateway, I can make calls no probs...

Just receiveing calls, i can talk.. and all is good.. just can't hear the incoming audio.

I did go to Google Voice and clicked on google chat and also (DISABLED the check box for mobile phone), but this did not fix the incoming audio issue.

Any ideas?
