I've checked in a change to the MGCP dissector to do exactly that.

If it is OK for an MGCP packet containing SDP data to be listed as
"MGCP/SDP" in the Protocol column - other protocols work that way, e.g. 
RTSP - then, as per my previous mail, the code to set the Protocol
column should be removed and the code to set the Info column should be
moved *before* the call to the SDP dissector, as the SDP dissector
appends to both of those columns, rather than overwriting them.
