I setup OBI with my existing Google voice number. Everything worked correctly. I then went thru process of porting landline to a Pay as you go t-mobile phone and then ported from t-mobile to GV. My landline number is now my GV number. I can call out and others can call in, but I now cannot call my new GV number from my regular cell phone.(worked ok with old GV #) Calls go directly to GVmail. My regular cell phone is in GV as a forwarding phone but forwarding box is not checked. Voicemail access is set to NO. Any help would be greatly appreciated.
