I hope I am posting in the right forum,
I am looking here to try to get help. Support abandoned me after telling me to remove all obitalk devices from my google voice account. After doing that, I had a difficult time getting all the phones back online. Support said they would all automagically reconnect, which was untrue!
Ever since this (which did not resolve the original problem) I can answer one incoming call (Google voice), but any other incomming calls will not ring the other phones while that call is active like it did before! I used to be able to have 2 incoming calls on the same GV number, now the line in use hears a call waiting beep instead of the other phones ringing.
I have contacted support for this issue, but they won't respond to emails or support requests! This is very disappointing, as I had been recommending their products up to this point. I had to figure out the other problem myself, and the solution had nothing to do with Google voice. It was a hardware issue with the OBI1022.
