2.8

Description (partial)

Symptom:
After upgrade to CMS 2.8, call is disconnected by VCS with error "Invalid syntax while parsing Session Description Protocol, expected" from VCS.

Conditions:
From CMS 2.8 on wards, FECC is supported and enabled by default. If the h224 clock rate doesn't match (the standard is 4800, not the 6400 the remote party has used here), CMS produces incorrect response in its SDP.
