The SIP Session Timer extension enables SIP sessions to be periodically

 

 

 

 

 

 

 

“refreshed” via a SIP request (UPDATE, or re-INVITE. Once the session interval

 

 

 

 

expires, if there is no refresh via a UPDATE or re-INVITE message, the session is

 

 

 

 

terminated.

out, provided no successful session refresh transaction occurs beforehand. The
