Session Timer
Session timer allows a periodic refresh of SIP sessions through a re-INVITE request, to determine whether a SIP
session is still active. Session timer is specified in RFC 4028. 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 request at or before the
negotiated session expiration.
Procedure
Session timer can be configured using the configuration files or locally.
To configure session timer via web user interface:
• Click on Account-> Advanced.
• Select the desired value from the Session Timer list.
• Enter the desired time interval in the Session Expires (30~7200s) field.
