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.
