[Neel] >From The RFC 4028 7. UAC Behavior 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. So, it is recommended to include option tag 'timer' in Supported header. In my opinion it is not a good idea to include new option tags in Require after the call is established. > > Thanks & Regards > -Meena > > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
