When I call my GV number via SIP, I go straight to the GV VM admin page - no questions asked. Is there anyway to route calls to the number over SIP and have the voicemail pickup for users to leave a message? Right now, I call out to a secondary GV number for VM services.
No, it's not possible to route calls into the Google Voice system through SIP, except in the way advertised--where you as the user are placing and receiving calls using your SIP endpoint.
You can forward calls to your registered devices via GVGW, but not into Google Voice.
