Description (partial)

When a multi-party video conference is established and an endpoint starts a H.239 session the CUCM clears the call.

CUCM Core files and clears calls

When multiple parties are on a conference, the MCU opens a logical channel for each party when the escalation to a H239 presentation is initiated by one of the parties. When an OLC is received concurrently with the processing of a prior OLC, the decode data buffer gets re-used and the processing of the preceding OLC references invalid data. This causes the CUCM to core.
