Ignore the Session-Expire header.

   A UAC that supports the session timer extension defined
here MUST
   include a Supported header field in each request (except
ACK),
   listing the option tag 'timer' [2].  It MUST do so even
if the UAC is
   not requesting usage of the session timer for this
session.

If the 'timer' is not indicated as supported,
you have to assume it isn't supported.

header.

Hi All,
               I have a query about Supported header. Is it
must to send
'timer' tag extension in Supported: header if
Session-Expire: 
60;refresher=uac/uas header is present in a request? 
   
  What should be the behaviour if UAS receives a message
including the
header "Session-Expire: 600;refresher=uac"but
excluding the header
"Supported:timer"?
   
  Thanks
  Shiv Shankar
