Under Incoming Calls on GV settings, three are listed as My Devices: Web, ObiTalk Device, Android, of which only the ObiTalk Device is enabled. For call forwarding, only Callcentric number was listed but is now disabled. The test call still just rang once and went to voice message.
I should add: the call history of both GV and Callcentric has logged the call. Given that I already disabled forwarding to Callcentric from GV, it's interesting that Callcentric would have the incoming call. I assume this has to do with Callcentric being registered with the Obi200?
Update: A call just came in with 2 rings and then disconnected itself. The call history of GV has this incoming call. However, the call history of Callcentric does not have it. This is different than the test call I made earlier. So, I made a test call (from my cell) again. As before, after one ring the recording came up. This call is registered into the call history of both GV and CC.
