Hi Antoine, The BYE request contains the two semicolon (;) before the To-tag. Retry the scenario after removing one extra semicolon before To-tag.
Thanks, Alok Tiwari Aricent -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Antoine Roly Sent: Monday, February 01, 2010 7:12 PM To: [email protected] Subject: [Sip-implementors] 481 Call/Transaction does not exist on BYE Hi, I'm trying to write a small scenario to simulate a basic SIP call, using SIPp. I have an error, the proxy between the two SIPp instances sends back a 481 message on the BYE. I probably missed something. I found a similar problem in the mailing list archive but can't determine the error in this case. Maybe it's an error with some tags parameters, or branch in the Via header. Here are the messages sent or received by the caller. Registrations have been done for both caller and callee FYI : the "_" at the end of lines come from the log file, they are not present in the real messages.
