o Session Expiration: The session timer enables SIP sessions to be periodically “refreshed”
via a SIP request. If enabled, before the session interval expires, the GXE502X will send a
SIP re-INVITE message to the SIP server. If this message is not replied to the session will
be terminated. This will avoid dropped sessions occupying the channel/bandwidth. Session
Expiration is the timer (in seconds) at which the session is considered timed out if no
successful session refresh transaction occurs beforehand. The default value is 180
seconds. Incorrect configuration could cause calls to be dropped or suspended.
o Min-SE: The minimum session expiration time (in seconds). The default value is 90
seconds.
