Not sure if question related to Megaco or H248. H248 does not discuss about call id of MGC. Call id is there in
SIP or similar call control procedures which are orthogonal to H.248. and H248 does not mandate any
specific call control application in MGC. Context-id is selected by MG and multiple terminations can be
in a context. Context id should not be confused or used as call-id in MGC, since for example a call with a call
id may be having terminations on multiple MGs controlled by same MGC. So same call id can have multiple
contexts in an MGC.

establishing a new call. Call ID is a hexadecimal string with a
maximum length of 32 characters. Call ID is unique within the MGC. Two
or more connections can have the same call ID if they belong to the
