I have a home cable based phone which is VOIP I am sure. If I try to dial from my cable phone to my GV numbers that are linked to my OBI, I get no ringer sound, just blank air until someone picks up or it goes to voicemail. I can't believe this has anything to do with Obi100 or Obi110, but I just thought I would ask here if anyone else is experience this.
If I dial from my cell phone, I hear the ringing until someone answers or it goes to voicemail. It seems to be only through this home Cable phone. If I call any other non-GV it rings after dialing those numbers just fine.
