Table 3-20: IP Group Parameters

The IP Group can be defined as one of the following types:

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.

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 (refer to
"Configuring the Outbound IP Routing Table" on page 142).
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 supports up to 100 registered users.
The device also supports NAT traversal for the SIP clients that
are behind NAT. In this case, the device must be defined with
a global IP address.
Note: This field is available only if the IP-to-IP application is
enabled.
