SIP Trunk betwee Call Manager 8.x and Siemens High Path 3800 PABX

Hi All,

 

Good evening. I have configured SIP Trunk between CUCM and Siemens High Path 3800 PABX. But when i dial the extension to the phone connected to siemens PABX, i dont get any dial tone and it gets dropped after 15 secs. The same issue is from the call coming to phone registered to CUCM from Phone connected to PABX. Kindly Suggest.

 

Thanks in Advance.

 

Regards

Sankar.

Have you checked the Run on

Have you checked the Run on all active nodes option in SIP trunk and Route List configurations? Can you check in RTMT Session Trace on which side is disconnecting the call and collect the ccm traces for a test call.
