Min-SE When two SIP devices negotiate a SIP session, they must
negotiate a common expiration time for idle SIP sessions.
This field sets the shortest expiration time that the router will
accept. The router checks the session expiration values of
incoming SIP INVITE requests against the minimum session
expiration value that you enter here. If the session expiration
of an incoming INVITE request is less than this value, the
router negotiates with the other SIP device to increase the
session expiration value to match the minimum session
expiration value.
Session Expires Refresher This determines which side of an expired call session will
initiate the session refresh.
uac – specifies the Caller side
will initiate the session refresh. uas – specifies the Call
receiver (the “Callee”) will initiate the session refresh..
