Table 3-14: IP Group Parameters
Parameter Description
Common Parameters
Type
[IPGroup_Type]
The IP Group can be defined as one of the following types:
ƒ
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.
ƒ
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). 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 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 SBC application is
enabled.
Description
[IPGroup_Description]
Brief string description of the IP Group.
The value range is a string of up to 29 characters. The default
is an empty field.
Proxy Set ID
[IPGroup_ProxySetId]
Selects the Proxy Set ID (defined in ''Configuring the Proxy
Sets Table'' on page
148 ) to associate with the IP Group. All
INVITE messages configured to be 'sent' to the specific IP
Group are in fact sent to the IP address associated with this
Proxy Set.
The range is 0-5, where 0 is the default Proxy Set.
Note: The Proxy Set is applicable only to SERVER-type IP
Groups.
SIP Group Name
[IPGroup_SIPGroupName]
The request URI host name used in INVITE and REGISTER
messages that are sent to this IP Group, or the host name in
the From header of INVITE messages received from this IP
Group. If not specified, the value of the global parameter
ProxyName (refer to ''Configuring the Proxy and Registration
Parameters'' on page
147 ) is used instead.
The value range is a string of up to 49 characters. The default
is an empty field.
