I have two OBi's (100 and 110) at different locations, both using the same GV number. I have set the inbound call routes to ring the attached phones and call the other Obi. I don't use any other google voice client. I can make calls from either Obi without problem, but it seems that when two incoming calls are close together that things break. Yesterday I had a incoming call, which rang both phones according to the Obitalk web portal, but an hour and a half later an incoming call did not ring at either one (one for sure, but the other Obi did not show the incoming call either). It seems that Google Voice send it straight to voicemail. Is this a Google Voice or Obi problem?
