Configuring IP Groups

The IP Group Table page allows you to create up to 32 logical IP entities called IP Groups.
An IP Group is an entity with a set of definitions such as a Proxy Set ID (see 'Configuring
Proxy Sets Table' on page 215), which represents the IP address of the IP Group.
IP Groups provide the following uses:

SIP dialog registration and authentication (digest user/password) of a specific IP
Group (Served IP Group, e.g., corporate IP-PBX) with another IP Group (Serving IP
Group, e.g., ITSP). This is configured in the Account table (see 'Configuring Account
Table' on page 241).

Call routing rules:
•
Outgoing IP calls (IP-to-IP or Tel-to-Tel): used to identify the source of the call
and used as the destination for the outgoing IP call (defined 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 (defined in 'Configuring Trunk Group Settings' on page 279).
•
Incoming IP calls (IP-to-IP or IP-to-Tel): used to identify the source of the IP call
•
Number Manipulation rules to IP: used to associate the rule with a specific calls
identified by IP Group

For the SBC application, IP Groups are used to classify incoming SIP dialog-initiating
requests (e.g., INVITE messages) to a source IP Group, based on Proxy Set ID
(defined in Configuring Classification Table on page 397). This occurs if the database
search for a registered user is unsuccessful. The classification process locates a
Proxy Set ID (associated with the SIP dialog request's IP address) in the Proxy Set
table, and then locates a match with an IP Group that is associated with this Proxy Set
in the IP Group table. This classification is enabled using the parameter Classify By
Proxy Set.
Notes:
SIP User's Manual
•
When operating with multiple IP Groups, the default Proxy server must
not be used (i.e., the parameter IsProxyUsed must be set to 0).
•
If different SRDs are configured in the IP Group and Proxy Set tables, the
SRD defined for the Proxy Set takes precedence.
•
You cannot modify IP Group index 0. This IP Group is set to default
values and is used by the device when IP Groups are not implemented.
•
You can also configure the IP Groups table using the ini file table
parameter IPGroup (see 'Configuration Parameters Reference' on page
547).
