Role in Trunk Group URI Feature

SIP header and parameter manipulation plays a role in the trunk group URI feature. You need to set the new-value parameter to one of the trunk group values when configuring SIP header rules, if using this feature. (In addition you can configure session agents and session agents groups on the Oracle® Enterprise Session Border Controller to insert trunk group URI parameters in the SIP contact header.

For all trunk group URI support, you must set the appropriate parameters in the SIP header manipulation configuration and in the session agent or session agent group configurations.

For trunk group URI support, the SIP header and parameter manipulation configuration tells the Oracle® Enterprise Session Border Controller where and how to manipulate the SIP message to use originating (access) and terminating (egress) trunk group URI parameters.
