User's Manual
Defines how the device handles registration messages and whether
Survivability mode is enabled for User-type IP Groups.

[0] Disable (default).

[1] Enable if Necessary = Survivability mode is enabled only if the
Serving IP Group is unavailable. The device saves in its
Registration database the registration messages sent by the
clients (e.g., IP phones) belonging to the User-type IP Group. If
communication with the Serving IP Group (e.g., IP-PBX) fails, the
User-type IP Group enters into Survivability mode in which the
device uses its database for routing calls between the clients of
the User-type IP Group. In Survivability mode, the RTP packets
between the clients always traverse through the device, and new
registrations can also be processed. When the Serving IP Group
is available again, the device returns to normal mode, sending
INVITE and REGISTER messages to the Serving IP Group.

[2] Always Enable = Survivability mode is always enabled. The
communication with the Serving IP Group is always considered
as failed. The device uses its database for routing calls between
the clients of the User-type IP Group.

[3] Always Terminate Register = The registration messages
received from the clients are saved in the device's registration
database without forwarding them to the proxy server. Upon
receipt of the registration message, the device returns a SIP 200
OK to the client.
Notes:

This parameter is applicable only to the IP-to-IP application.

This parameter is applicable only to User-type IP Groups.
If configured, INVITE messages initiated from the IP Group are sent
to this Serving IP Group (range 1 to 9). In other words, the INVITEs
are sent to the address defined for the Proxy Set associated with this
Serving IP Group. The Request-URI host name in the INVITE
messages are set to the value of the 'SIP Group Name' parameter
defined for the Serving IP Group.
Notes:

This parameter is applicable only to the IP-to-IP application.

If the PreferRouteTable parameter is set to 1, the routing rules in
the Outbound IP Routing table take precedence over this 'Serving
IP Group ID' parameter.

If this parameter is not configured, the INVITE messages are sent
to the default Proxy or according to the Outbound IP Routing
table.
Defines whether the incoming INVITE is classified to the IP Group
according to its associated Proxy Set.

[0] Disable

[1] Enable (default)
This classification occurs only if classification according to the
device's database fails to (i.e., received INVITE is not from a
registered user). The classification proceeds with checking whether
the INVITE's IP address (if host names, then according to the
dynamically resolved IP address list) is defined for a Proxy Set ID (in
the Proxy Set table). If a Proxy Set ID has such an IP address, the
