The scenario, Obi110 has a pstn. SP1 set to GV. This is just a generic setup. When I make a phone call which is through GV, if someone calls the pstn line while I'm making a call, they get a ring tone rather then a busy signal. My questions are:
1. Is there a way for the person calling to get a busy signal?
2. Better yet, is there a way to forward the call to GV voicemail?
