Configuring IP Groups

The IP Groups table lets you configure up to 625 IP Groups. An IP Group represents a SIP
entity in the network with which the device communicates. This can be a server (e.g., IP
PBX or ITSP) or a group of users (e.g., LAN IP phones). For servers, the IP Group is
typically used to define the server's IP address by associating it with a Proxy Set (see
Configuring Proxy Sets on page 338).
You can use IP Groups for the following:

Classification of incoming SIP dialog-initiating requests (e.g., INVITE messages) to IP
Groups based on Proxy Set. If the source address of the incoming SIP dialog is
defined for a Proxy Set, the device assigns ("bonds") the SIP dialog to the IP Group
associated with the Proxy Set. The feature is configured using the IP Groups table's
'Classify by Proxy Set' parameter. For more information and recommended security
guidelines, see the parameter's description, later in this section.

Representing the source and destination of the call in IP-to-IP Routing rules (see
Configuring SBC IP-to-IP Routing Rules on page 464).

SIP dialog registration and authentication (digest user/password) of specific IP Groups
(Served IP Group, e.g., corporate IP-PBX) with other IP Groups (Serving IP Group,
e.g., ITSP). This is configured in the Accounts table (see ''Configuring Registration
Accounts'' on page 351).

Included in routing decisions by a third-party routing server. If deemed necessary for
routing, the routing server can even create an IP Group. For more information, see
Centralized Third-Party Routing Server on page 263.
You can also apply the device's Quality of Experience feature to IP Groups:

Quality of Experience Profile: Call quality monitoring based on thresholds for voice
metrics (e.g., MOS) can be applied per IP Group. For example, if MOS is considered
poor, calls belonging to this IP Group can be rejected. To configure Quality of
Experience Profiles, see ''Configuring Quality of Experience Profiles'' on page 289.

Bandwidth Profile: Bandwidth utilization thresholds can be applied per IP Group. For
example, if bandwidth thresholds are crossed, the device can reject any new calls on
this IP Group. To configure Bandwidth Profiles, see ''Configuring Bandwidth Profiles''
on page 294.
User's Manual
the SRD associated with the SIP Interface is applied.

[0] Disable = The device rejects REGISTER requests from new
users that were not authenticated by a proxy server.

[1] Enable = The device accepts REGISTER requests from new
users even if they were not authenticated by a proxy server, and
registers the user in its registration database.
Note:

Regardless of the parameter, the device always accepts
registration refreshes from users that are already registered in its
database.

If configured to Disable or Enable, the parameter overrides the
'Enable Un-Authenticated Registrations' parameter settings of the
SRD (in the SRDs table) that is associated with the SIP Interface.
Defines the maximum number of users belonging to the SIP
Interface that can register with the device.
By default, no value is defined (i.e., the number of allowed user
registrations is unlimited).
