I'm using a Cisco IP Phone 7960 Series using SIP. Moreover, I'm using a SIP proxy server OnDO and CiscoAS5350 and Voice Master. My call flow was IP Phone-->OnDO-->VM-->CiscoAS5350. My call went thru and the quality is good yet i got no ringback, i called my mobile phone and its ringing yet i can't hear anything from IP Phone. Could you tell me why this happen. i try to use debug command and seems to be fine. Any idea about why it has no ringback?
