The last couple days, placing calls via GV has been hit or miss, mostly miss. (No problems placing calls on other carriers.) My incoming calls don't go through SP1/GV, but are forwarded to a DID with a commercial VoIP carrier on SP2 or SP3. (I use two of them.) This morning wasn't able to call anyone on Google Voice. SP1 (GV) Service Status was "Connected" the whole time. I rebooted the Obi2xx and was then able to place a call.
Any idea what's going on? I've never seen this behavior in years of using Google Voice.
