Description (partial)

When Synergy endpoints call into CTMS Telepresence Servers, and call traverses a UCM via trunk to trunk, the UCm doesn't not always properly relay the contact header parameters required for proper call signaling.

Telepresence call is established temporarily, but then is abnormally ended.

Definitely impacts synergy (DX650, DX80, DX70) interop with CTMS servers.
May also impact interop between CTMS and other endpoint variants (EX60/EX90, and CTS).
