About six months ago, I purchased an ObiHai and set it up with GV. I also configured a free DID (914) Callcentric number to do 911/CNAM using the setup instructions on this forum. Outbound calls were straight through GV and inbound calls were forwarded to CC.
This setup seemed to work great at first, but then some of my friends began to complain about long delays before the phone would ring. I began testing inbound calls and the delays could be 45+ seconds before the phone began to ring, if it rang at all. Sometimes the caller would never get through and would be stuck in an endless ringing loop. Other times everything worked fine. I could make a call one minute and had no issues. After hanging up, I would ring my number again and experience a long delay or no ringing at all. Nothing made sense.
I updated the firmware on the ObiHai and completely reset the device several times, but it made no difference. After reading about other people having issues on this forum a while back, I decided to pull Callcentric out of the config. All of my problems instantly went away and Obi+GV has worked flawlessly ever since. Clearly there is a forwarding issue between GV and CC for some users, but I had no luck trying to work with CC on it. They didn't seem to think the issue was on their side, which could be true.
Are people still experiencing issues like this? What is your current experience like if you are forwarding to CC from GV? What free DID area code did you receive? I really would like to have CNAM or at least the ability to identify a few friends by name on my phone. But, if there are still strange issues between CC and GV, then I can still live without it.
