When you attempt to make a connection by sending a SETUP message, you dont have a connection identifier at this point of time. Your attempt may succeed in which case you will receive the connection identifier in the first message returned by the network say CALL PROCEEDING. If for some reason the network is not able to make a connection and it sends a RELEASE COMPLETE message, then there should be some way for the user side to find out this RELEASE COMPLETE was for which SETUP. This is when the call ref value comes into picture. Also remember that a connection is the obtained as a result of making a call. You may succeed or fail in your attempt to make a connection. But there should be always some means of associating every message returned by the Network with a call, which is done by the Call Reference. Hope this helps.
