Session Timer - Yealink SIP-T46G Administrator's Manual

7.
The session timer feature allows for a periodic refresh of SIP sessions through a re-INVITE
or an UPDATE request to determine whether the SIP session is still active. Session timer is
specified in RFC 4028. The IP phones support two refresher modes: UAC and UAS. The
UAC mode means refreshing the session from the client, while the UAS mode means
refreshing the session from the server. The session expiration and session refresher are
negotiated via the Session-Expires header in the INVITE message. The negotiated
refresher will send a re-INVITE/UPDATE message at or before the negotiated session
expiration.
