SIP TRUNK BETWEEN FREEPBX AND CUCM6

Hi experts,

I have configured sip trunk between freepbx and cucm6 and was successfully done. But problem is that when I try to call cisco ip phone from sip phone and hangup sip phone after 1 or 2 rings, cisco ip phone remains ringing and after sometime it get hangup. How can I resolve this ringing issue after sip phone hangsup?

regards,

RAHIL

SIP TRUNK BETWEEN FREEPBX AND CUCM6

If you hang up before the destination answers the source should send a SIP CANCEL message. If you have answered it would then need to be a BYE message. Take a wireshark or enable troubleshooting traces in CUCM and take a look at the SIP dialog. Feel free to attach the traces to this thread if you want a second look at them.

check the traces and we are getting the cancel message..

cisco ip phone is sccp phone, so need to check traces for the sccp side as well to confirm what we are doing once we are getting the cancel message.

thanks,
