Configuring IP Groups
The IP Groups table lets you configure up to 80 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 address of the IP Group is typically defined
by associating it with a Proxy Set (see Configuring Proxy Sets).
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 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.
■ (SBC Application ) Classification of incoming SIP dialog-initiating requests (e.g., INVITE
messages) to IP Groups based on source tags of incoming dialog. Tag-based classification
occurs only if Classification based on user registration and on Proxy Sets fail. For more
information, see Configuring Classification Based on Tags on page770.
■ (SBC Application) Representing the source and destination of the call in IP-to-IP Routing rules
(see Configuring SBC IP-to-IP Routing Rules).
■ 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).
■ (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).
● 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-Tel Routing Rules).
● Number manipulation: The IP Group can be associated with a number manipulation rule
(see Configuring Number Manipulation Tables).
■ 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.
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.
■ 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.
● For the Gateway application, IP Group #0 cannot be associated with Proxy Set #0.
● If you delete an IP Group or modify the 'Type' or 'SRD' parameters, the device
immediately terminates currently active calls that are associated with the IP Group.
In addition, all users belonging to the 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 > ip-group).
