In forking if OK is recived from more than 1 user,   then have to accept the single user and need to cancel other ,  but the CANCEL will not work after the UAS has responded with OK, then how we can cancel later recvd OK response , such transactions can we call its session as it as already sent response, whats the method to handle such case.-santoshOn Wed, 29 Apr 2009 11:51:37 -0500 Manish Aggarwal wrote3261 says ---CANCEL has no effect on a request to which a UAS hasalready given a final response.So, if UAC has received a 2XX response to INVITE, than CANCEL will not have any effect, because there is no "pending" request.-ManishOn Wed, Apr 29, 2009 at 5:12 AM, Jyothi Laxmish wrote:Hi all             (1) Is it possible to send a CANCEL message when call is in established stage?( INV to ACK )                                 I am receiving 481 call Leg/Transaction does notexists.
