Description
Enter the frequency in which the system informs the
SIP proxy that it is active by re-sending the details of
all conference types to the server. If the various
conferences and Entry Queues do not register within
the defined time interval, the SIP server will not refer
calls to this conference/Entry Queue until it re-
registers. If timeout is set to 0, re-registration is
disabled.
The default value is 3600 seconds (60 minutes).
