Description (partial)

Issue in processing MER caps due of absence a=vndpar line in the Incoming INVITE. Due to this V.150 caps are not passed to the other side and the call fails.

Symptom:
Call initiated between two SIP endpoints registered to REDCOM HDX. 
Call fails after CUCM sends 200 OK to initiator as SIP is not able to pass V.150 caps received in initial INVITE's SDP.

Conditions:
Incoming INVITE with MER caps without a=vndpar line
