Abstract:
A method for correlating call signaling messages associated with multiple calls and sent over a single network connection, the method comprising:(a) at a first call agent, formulating a first call signaling message associated with the first call, the fist call signaling message having a first half call ID including a first allocation parameter for indicating a call originator and a first call counter for identifying the first call; (b) setting the first allocation parameter to a first value for identifying the first call agent as originator of the first call and the first call counter to a first count value for identifying the first call; (c) transmitting the first call signaling message to a second call agent over a first network connection; (d) at the second call agent, in response to receiving the first message, formulating a second call signaling message including a second half call ID having a second allocation parameter and a second call counter; (e) setting the second allocation parameter to a second value for identifying the second call agent as non-originator of the first call and setting the second call counter to the first count value; and (f) transmitting the second call signaling message to the first call agent over the first network connection.
