9.2.5.2 SIP URI Manipulation
The example in this subsection enhances the configuration described in ''SBC
Configuration Example'' on page 468 to includ
e the manipulation feature for SBC SIP URI
user and host parts. In this example, the following manipulations are performed:
îš„ SIP URI host part: for the SIP INVITE sent from any source destination IP Group (i.e.,
USER IP Group ID #1) to the IP PBX (i.e., IP Group ID #2), the URI host name is
replaced with "IPBX" in the outgoing INVITE to the WAN. This configuration is
performed in the 'IP Group' table pertaining to the IP Phones.
îš„ SIP URI user part: for the SIP INVITE containing the destination URI user name prefix
"976", sent from the USER IP Group, the prefix is removed (i.e., "976") in the outgoing
INVITE to the WAN. This configuration is performed in the 'IP2IP Inbound
Manipulation' page.
The procedure below describes how to configure these SIP URI manipulations.
¾ To configure SIP URI manipulations according to the above scenario
example:
1. To configure the SIP URI host part manipulation:
a. Open the 'IP Group Table' page (Configuration tab > Protocol Configuration
menu > Proxies/IpGroups/Registration submenu > IP Group Table).
b. From the 'Index' drop-down list, select the IP Group representing the enterprise's
IP Phones (i.e., USER IP Group ID #1).
c. In the 'SIP Group Name' field, enter "IPBX". All SIP messages sent from this IP
Group replaces the SIP URI host part with this value.
