Determines whether Survivability mode is enabled for USER-type IP
Groups.

[0] Disable (default).

[1] Enable if Necessary = Survivability mode is enabled. The device
records in its database the registration messages sent by the
clients 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 (e.g., IP phones) of
the USER-type IP Group. The RTP packets between the IP phones
in Survivability mode always traverse through the device. In
Survivability mode, the device is capable of receiving new
registrations. 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 (e.g., IP-PBX) is always
considered as failed. The device uses its database for routing calls
between the clients (e.g., IP phones) of the USER-type IP Group.
Notes:

This field is available only if the SBC or IP-to-IP application is
enabled.

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 field is available only if the SBC or IP-to-IP application is
enabled.

If the parameter PreferRouteTable is set to 1, the routing rules in
the 'Outbound IP Routing Table' takes 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'.
Determines whether the incoming INVITE is classified to an IP Group
according to the Proxy Set.

[0] Disable

[1] Enable (default)
This classification occurs only if classification according to the device's
database fails for locating whether the INVITE arrived 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 in the IP Group's Proxy Set ID (in
the Proxy Set table). If the IP address is listed, then the INVITE is
assigned to this IP Group.
