Abstract

A method and apparatus for multi-media communication includes transmitting a first session invite request (300) having a plurality of first call transaction identifiers (302), wherein each of the first call transaction identifiers (302) has a first call transaction value (303). Thereupon, the method and apparatus engages in a first communication session using the first session invite request (300). Concurrently, a second session invite request (400), having a plurality of second call transaction identifiers (402) having a second call transaction value (403), is also transmitted. A determination is made if the second session invite request (400) is duplicative by comparing the first and second call transaction values (303, 403) of the first and second call transaction identifiers (302, 402). A second communication session is engaged if the second session invite request (400) is not duplicative such that the first communication session and the second communication session create a multi-media session.
