I have an OBI200. SP1 Google Voice, SP2 OBI Phonepower. I use the Google Voice webpage to initiate calls. When I try to place a call, the interface allows me to connect via Google Talk, with my cell phone or with Hangouts. All of the options except Google Talk work. If I select Google Talk, which used to connect to my cordless phone that is connected to the OBI200, I get Invalid Number. Help!
