Configuring IP Groups

The IP Group table lets you configure up to 102 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 362).
You can use IP Groups for the following:

SBC application: 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
Group table's 'Classify by Proxy Set' parameter. For more information and
recommended security guidelines, see the parameter's description, later in this
section.SBC application: Representing the source and destination of the call in IP-to-
IP Routing rules (see Configuring SBC IP-to-IP Routing Rules on page 653).

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 Account table (see ''Configuring Registration
Accounts'' on page 371).

Gateway application: Call routing rules:
•
Tel-to-IP calls: The IP Group is used as the destination of the outgoing IP call and
is used in Tel-to-IP call routing rules (see Configuring Tel-to-IP Routing Rules on
page 495).
•
IP-to-Tel calls: The IP Group identifies the source of the IP call and is used in IP-
to-Tel call routing rules (see Configuring IP-to-Trunk Group Routing Rules on
page 506).
•
Number manipulation: The IP Group can be associated with a number
manipulation rule (see Configuring Number Manipulation Tables on page 469).

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 280.
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. For configuring Quality of
Experience Profiles, see ''Configuring Quality of Experience Profiles'' on page 313.

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. For configuring Bandwidth Profiles, see ''Configuring Bandwidth
Profiles'' on page 317.
Note:
immediately terminates currently active calls associated with the IP Group. In addition,
all users belonging to this IP Group are removed from the device's users database.
The following procedure describes how to configure IP Groups through the Web interface.
You can also configure it through ini file (IPGroup) or CLI (configure voip > control-network
ip-group).
