Krishna, By including this header the UAC requests UAS to enable session timers described in details in RFC4028. Support for this RFC is completely optional in SIP 2.0, so that UAS might safely ignore this header if it doesn't implement this feature. Otherwise, it should follow procedures set forth in the said RFC. Regards, -- Maksym Sobolyev Sippy Software, Inc.
