Hi Varun, An INVITE that is forked can cause multiple dialogs to be established with different UASs. If the UAC has sent an INVITE and wishes to terminate the whole session, it can send a CANCEL. The CANCEL terminates the INVITE transaction and hence, all the early dialogs established due to it are terminated.
If the UAC wants to only terminate specific early dialogs that are created due to this INVITE, without terminating the whole session, it can send BYEs to the specific UASs and terminate the early dialogs with them.

Does thats sound right? Generally you would send CANCEL to terminate an early dialog(means you have got a provisional response like 180).
