User's Manual
representing multiple users. This IP Group type is necessary for any
of the following scenarios:

The IP Group cannot be defined as a Server-type since its
address is initially unknown and therefore, a Proxy Set cannot be
configured for it.

The IP Group cannot be defined as a User-type since the SIP
Contact header of the incoming REGISTER does not represent a
specific user. The Request-URI user part can change and
therefore, the device is unable to identify an already registered
user and therefore, adds an additional record to the database.
The IP address of the Gateway-type IP Group is obtained
dynamically from the host part of the Contact header in the
REGISTER request received from the IP Group. Therefore, routing to
this IP Group is possible only once a REGISTER request is received
(i.e., IP Group is registered with the device). If a REGISTER refresh
request arrives, the device updates the new location (i.e., IP address)
of the IP Group. If the REGISTER fails, no update is performed. If an
UN-REGISTER request arrives, the IP address associated with the
IP Group is deleted and therefore, no routing to the IP Group is done.
You can view the registration status of the Gateway-type IP Group in
the 'GW Group Registered Status' field, and view the IP address of
the IP Group in the 'GW Group Registered IP Address' field if it is
registered with the device.
Assigns a Proxy Set to the IP Group. All INVITE messages destined to
the IP Group are sent to the IP address configured for the Proxy Set.
To configure Proxy Sets, see 'Configuring Proxy Sets' on page 380.
Note:

For the Gateway application: IP Group ID 0 cannot be associated
with Proxy Set ID 0.

The Proxy Set must be associated with the same SRD as that
assigned to the IP Group.

You can assign the same Proxy Set to multiple IP Groups.

For the SBC application: Proxy Sets are used for Server-type IP
Groups, but may in certain scenarios also be used for User-type IP
Groups. For example, this is required in deployments where the
device mediates between an IP PBX and a SIP Trunk, and the SIP
Trunk requires SIP registration for each user that requires service. In
such a scenario, the device must register all the users to the SIP
Trunk on behalf of the IP PBX. This is done by using the User Info
table where each user is associated with the source IP Group (i.e.,
the IP PBX). To configure the User Info table, see SBC User
Information for SBC User Database on page 852.

For the Gateway application: Proxy Sets are applicable only to
Sever-type IP Groups.
Assigns an IP Profile to the IP Group.
By default, no value is defined.
To configure IP Profiles, see 'Configuring IP Profiles' on page 436.
Assigns a Media Realm to the IP Group. The Media Realm determines
the UDP port range and maximum sessions on a specific interface for
media traffic associated with the IP Group.
By default, no value is defined.
