Abstract:
1. A method for associating call legs in a network, the method comprising: a first endpoint generating a first enhanced call-id for a communication session with a second endpoint, the first enhanced call-id comprising a first shared call-id and a first unique identifier; the first endpoint sending the first enhanced call-id to a Back to Back User Agent (“B2BUA”); the B2BUA generating a first call leg between the first endpoint and the second endpoint using the first enhanced call-id; the first endpoint generating a second enhanced call-id to join a third endpoint to the communication session, the second enhanced call-id comprising a second shared call-id and a second unique identifier; the first endpoint sending the second enhanced call-id to the B2BUA; the B2BUA generating a second call leg between the first endpoint and the third endpoint using the second enhanced call-id; the third endpoint generating a third enhanced call-id, the third enhanced call-id comprising a third shared call-id and a third unique identifier; the third endpoint sending the third enhanced call-id to the B2BUA; and the B2BUA generating a third call leg between the third endpoint and the second endpoint using the third enhanced call-id; and wherein the first call leg, the second call leg, and the third call leg together comprise a conference between the first endpoint, the second endpoint, and the third endpoint; and wherein the first unique identifier corresponds to the first endpoint, the second unique identifier corresponds to the second endpoint, and the third unique identifier corresponds to the third endpoint.
