3.4.7.6.3 Configuring the IP Groups
The 'IP Group Table' page allows you to create up to nine logical IP entities (IP Groups)
that are later used in the call routing tables. The IP Groups are typically implemented in Tel-
to-IP call routing. The IP Group can be used as a destination entity in the 'Tel to IP Routing'
table (or 'Outbound IP Routing Table'), and Serving IP Group ID in the 'Trunk Group
Settings' (refer to ''Configuring the Trunk Group Settings'' on page
197 ) and 'Account' (refer
to ''Configuring the Account Table'' on page 204 ) tables. These call routing tables are used
for identifying the IP Group from where the INVITE is sent for obtaining a digest
user/password from the 'Account' table if there is a need to authenticate subsequent SIP
requests in the call. The IP Group can also be implemented in IP-to-Tel call routing (or
inbound IP routing) as a source IP Group.
The IP Groups are assigned various entities such as a Proxy Set ID, which represents an
IP address (created in ''Proxy Sets Table'' on page
141 ). You can also assign the IP Group
with a host name and other parameters that reflect parameters sent in SIP Request
From\To.
Notes:
•
By default, if you disable the use of a proxy (i.e., IsProxyUsed is set to 0),
then only one IP Group is defined (and working with multiple IP Groups is
not valid).
•
You can also configure the IP Groups table using the
ini
file table
parameter IPGroup (refer to ''SIP Configuration Parameters'' on page
284 ).
