Hi,
RFC 4028 states that, for the subsequent session refresh requests "The values of Supported, Require, and Proxy-Require used in the initial Session refresh request MUST be used." If the subsequent refresh requests does not add any of these headers, Would it still use the values in the initial request (initial INVITE)? Is the below scenario a valid scenario ---The initial INVITE carries all these headers and the subsequent refresh INVITEs has none of these headers Why does RFC mandate that these headers must be used in the subsequent requests? _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
