Re: MGCP-Query regarding Connection id and call id?

I have seen a sample trace of 3way call.Following is the flow,please
correct me if i am wrong:

A dials B first a 2way call is established and the details of this
call are say call id value from Call agent comes as 1 and connection
id generated by endpoint   is 10

Now A presses flash hook

Now A dials C and 2way call is established and the details of this
call are say call id value from Call agent comes as  2 and connection
id generated by endpoint   is 11

A presses flash hook again.Call agent changes the Connection mode
parameter to "conference" via the MDCX
command for entity A and a conference call is established b/s the 3 parties.

Here different connection id  is used during the conf. call.

Sumant
