Please clarify this query.........

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?
   
  Thanks & Regards,
  Shiv Shankar

Hi,
The Supported header is used to convey that the UAC supports
session 
timers. If the UAC supports Session timers, according to the
RFC 4028 it 
is a MUST that Supported:Timer header be present. If the UAC
does not 
support Session Timers but requires that the UAS support
session timers, 
there should be a Required: timer header present in the
request.
