17.5 Configuring IP Groups
The IP Group table lets you configure up to 50 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 it can be 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
274 ).
IP Groups can be used 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
487 ).

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
281 ).

Gateway application: Call routing rules:
•
Outgoing IP calls (IP-to-IP or Tel-to-IP): The IP Group identifies the source of the
call and is used as the destination of the outgoing IP call (configured in the
Outbound IP Routing table). For Tel-to-IP calls, the IP Group (Serving IP Group)
can be used as the IP destination to where all SIP dialogs that are initiated from a
Trunk Group are sent (configured in Configuring Hunt Group Settings on page
355 ).
•
Incoming IP calls (IP-to-IP or IP-to-Tel): The IP Group identifies the source of the
IP call.
•
The IP Group can be used to associate a number manipulation rule with specific
calls identified by IP Group.
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
240 .

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
244 .
Notes:
•
IP Group ID 0 cannot be used. This IP Group is set to default values and is used
by the device when IP Groups are not implemented.
•
If different SRDs are configured in the IP Group and Proxy Set tables, the SRD
defined for the Proxy Set takes precedence.
The following procedure describes how to configure IP Groups in the Web interface. You
can also configure IP Groups using the table ini file parameter, IPGroup or CLI command,
configure voip > control-network ip-group.
