Can somebody help in providing info that how can a single callid could
have 2 more or connections associated with it?

Some text i have found:

A call is identified by its call ID, which is created by the MGC when
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
same call.

Looking for response?
