Hi All,
We have 7975 SIP phone registered to CUCM 8.6 and CUCM has SIP trunk pointed to CME. Phone from CUCM side calls CME phone, and it rings fine but when we are doing multiple time hold/resume, call is disconnected with the following error message:
SIP/2.0 400 Bad Request
Warning: 399 Invalid SDP
It seems for the first couple of hold/resume, CUCM is sending complete SDP and they are fine, but after multiple times, SDP is not being sent from CUCM to CME.
Any suggestion would be appreciated.
Alex
