Description
Enter the frequency in which the system informs the
SIP proxy that it is active by re-sending the details of
all registered conferencing elements to the server.
If the registration is not renewed within the defined
time interval, the SIP server will not refer calls to the
conferencing entity until it reregisters. If timeout is
set to 0, re-registration is disabled.
The default value is 3600 seconds (60 minutes).
Select the protocol that is used for signaling
between the MCU and the SIP Server or the
endpoints according to the protocol supported by
the SIP Server:
UDP – Select this option to use UDP for signaling.
TCP – Select this option to use TCP for signaling.
If the SIP Server supports both protocols, select the
one that is most suitable.
If the selected protocol is TCP and the endpoint that
is behind the proxy supports UDP, the server knows
how to send and receive the signaling from the
endpoint in UDP, even if it is defined as TCP.
Note: Transferring signaling directly to this endpoint
will fail as its protocol its different from the selected
protocol.
Enter the IP address of the preferred SIP server.
