I've got an OBi202 connected to a Cisco (Linksys) SPA962 IP phone configured with google Voice exactly as detailed in this article: http://blog.obihai.com/2012/08/use-your-obi202-as-google-voice-gateway.html
Everything is working great except for one major issue: When I make outgoing calls, it will ring the number being called but if no one answers the call after about 8 rings, the ringing stops and goes silent, and my IP phone displays "connected". But it never goes to voice mail. So basically I can never leave a voice mail message for anyone I make out gong calls to. Any help would be greatly appreciated - this is driving me crazy!
I have the same issue except i set it up with the cisco uc320 outgoing calls go to voice mail every time when placed from a phone connected to the obi phone port but when placed through the a phone connected to the uc320 some numbers continue to ring and dont get voice mail while other numbers always get voice mail
did you ever figure out what is causing this?
