Media Release between Endpoints with the Same IP Address

You can configure your Oracle® Enterprise Session Border Controller to release media between two endpoints even when one of them:

• Is directly addressable at the same IP address as a NAT device, but is not behind a NAT device
• Is at the same IP address of a NAT device the other endpoint is behind

You enable this feature on a per-realm basis by setting an option in the realm configuration.

When this option is not set, theOracle® Enterprise Session Border Controller will (when configured to do so) release media between two endpoints sharing one NAT IP address in the same realm or network.

Media Release Configuration

In order for this feature to work properly, the following conditions apply for the realm configuration:

• Either the mm-in-realm or the mm-in-network parameter must be disabled; you can have one of these enabled as long as the other is not. The new option will apply to the parameter that is disabled.
• If either the mm-in-realm or mm-in-network parameter is enabled, then the mm-same-ip parameter must be disabled.

To enable media release between endpoints with the same IP address:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal
   ORACLE(configure)#

2. Type media-manager and press Enter.

   ORACLE(configure)# media-manager
   ORACLE(media-manager)#

3. Type realm-config and press Enter.

   ORACLE(media-manager)# realm-config

   If you are adding support for this feature to a pre-existing realm, then you must select (using the ACLI select command) the realm that you want to edit.

4. options—Set the options parameter by typing options, a Space, the option name release-media-at-same-nat with a plus sign in front of it, and then press Enter.

   ORACLE(realm-config)# options +release-media-at-same-nat

   If you type the option without the plus sign, you will overwrite any previously configured options. In order to append the new options to the realm configuration’s options list, you must prepend the new option with a plus sign as shown in the previous example.

5. Save and activate your configuration.
