Hello Everybody,

 

I have a question about the RFC4028 session timer of invite usage. The section 
7.1 says: 

 

7.1.  Generating an Initial Session Refresh Request

   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.

 

Does it mean all the requests created by the UAC must include the Supported 
header with tag ‘timer’? For example, the UPDATE request for SDP change also 
need include ‘timer’ tag in Supported header? And the BYE request also need 
include 'timer' tag? 

 

Thanks in advance.

 

Best Regards,

Terry Song
