Enables the IP Group to be used by a third-party routing server for call
routing decisions.

[0] Not Used (default)

[1] Used
For more information on the third-party routing server feature, see
Centralized Third-Party Routing Server on page 294.
(Read-only field) Displays the connectivity status with Server-type IP
Groups. As the Proxy Set defines the address of the IP Group, the
connectivity check (keep-alive) by the device is done to this address.

"NA": Functionality is not applicable due to one of the following:

User-type IP Group.

Server-type IP Group, but the keep-alive mechanism of its'
associated Proxy Set is disabled.

"Not Connected": Keep-alive failure (i.e., no connectivity with the IP
Group).

"Connected": Keep-alive success (i.e., connectivity with the IP
Group).
The connectivity status is also displayed in the Topology View page (see
'Building and Viewing SIP Entities in Topology View' on page 388).
Note:

The feature is applicable only to Server-type IP Groups.

To support the feature, you must enable the keep-alive mechanism of
the Proxy Set that is associated with the IP Group (see 'Configuring
Proxy Sets' on page 380).

If the Proxy Set is configured with multiple proxies (addresses) and at
least one of them is "alive", the displayed status is "Connected". To
view the connected proxy server, see 'Viewing Call Routing Status'
on page 947.

The "Connected" status also applies to scenarios where the device
rejects calls with the IP Group due to low QoE (e.g., low MOS),
despite connectivity.
Enables classification of incoming SIP dialogs (INVITEs) to Server-type
IP Groups based on Proxy Set (assigned using the
IPGroup_ProxySetName parameter).

[0] Disable

[1] Enable = (Default) The device searches the Proxy Sets table for a
Proxy Set that is configured with the same source IP address as that
of the incoming INVITE (if host name, then according to the
dynamically resolved IP address list). If such a Proxy Set is found,
the device classifies the INVITE as belonging to the IP Group
associated with the Proxy Set.
Note:

The parameter is applicable only to Server-type IP Groups.

For security, it is recommended to classify SIP dialogs based on
Proxy Set only if the IP address of the IP Group is unknown. In other
words, if the Proxy Set associated with the IP Group is configured
with an FQDN. In such cases, the device classifies incoming SIP
dialogs to the IP Group based on the DNS-resolved IP address. If the
IP address is known, it is recommended to use a Classification rule
