IP Group Parameters
Defines the type of IP Group:

[0] Server = Used when the destination address, configured by the
Proxy Set, of the IP Group (e.g., ITSP, Proxy, IP-PBX, or Application
server) is known.

[1] User = Represents a group of users such as IP phones and
softphones where their location is dynamically obtained by the device
when REGISTER requests and responses traverse (or are
terminated) by the device. These users are considered remote (far-
end) users.
Typically, this IP Group is configured with a Serving IP Group that
represents an IP-PBX, Application or Proxy server that serves this
User-type IP Group. Each SIP request sent by a user of this IP Group
is proxied to the Serving IP Group. For registrations, the device
updates its internal database with the AOR and contacts of the users.
Digest authentication using SIP 401/407 responses (if needed) is
performed by the Serving IP Group. The device forwards these
responses directly to the SIP users.
To route a call to a registered user, a rule must be configured in the
Outbound IP Routing Table. The device searches the dynamic
database (by using the request URI) for an entry that matches a
registered AOR or Contact. Once an entry is found, the IP destination
is obtained from this entry, and a SIP request is sent to the
destination.
The device also supports NAT traversal for the SIP clients located
behind NAT. In this case, the device must be defined with a global IP
address.
Note: This field is applicable only to the IP-to-IP application.
Defines a brief description for the IP Group.
The valid value is a string of up to 29 characters. The default is an empty
field.
Assigns a Proxy Set ID to the IP Group. All INVITE messages destined
to this IP Group are sent to the IP address configured for the Proxy Set.
Notes:

Proxy Set ID 0 must not be used; this is the device's default Proxy.

The Proxy Set is applicable only to Server-type IP Groups.

The SRD configured for this Proxy Set in the Proxy Set table is
automatically assigned to this IP Group (see the 'SRD' field below).

To configure Proxy Sets, see 'Configuring Proxy Sets Table' on page
209.
Defines the SIP Request-URI host name used in INVITE and REGISTER
messages sent to this IP Group, or the host name in the From header of
INVITE messages received from this IP Group.
The valid value is a string of up to 100 characters. The default is an
empty field.
Notes:

If this parameter is not configured, the value of the global parameter,
ProxyName is used instead (see 'Configuring Proxy and Registration
Parameters' on page 218).
