Session Agent Ping Message Formatting
You can configure the user portions of the Request-URI and To: headers that define the destination of a session agent ping message, and the From: header that defines the source of a session agent ping message. These headers are sent to Oracle Communications Session Border Controller session agent. This feature is required for interoperability with certain E911 servers.
In the following example of a session agent ping-type message, you can set the user portion of the Request-URI (the text bob in the OPTIONS method line) and the user portion of the From: header (the text bob in the From: header) to the same new value. You can also set the user portion of the To: header (the text anna in the To: header) to its own new value.

If you do not enable this feature, then the session agent ping-type message contains the text ping in all cases.
