The IP phones support to use session timer to send periodic re-INVITE requests to refresh
the session during a call. The session timer is defined in RFC 4082. 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.
