Media Release Behind the Same NAT IP Address

You can now configure your Oracle® Enterprise Session Border Controller to release media between endpoints sharing the same NAT IP address, even if one endpoint is at—but not behind—the same NAT. This feature expands on the Oracle® Enterprise Session Border Controller’S pre-existing ability to release media between calling and called parties behind the same IP address/NAT device in the same realm or network.

Media Release Configuration

For this feature to work properly, your realm configuration should either have the mm-in-realm or mm-in-network parameter set to disabled, unless the mm-same-ip parameter is set to disabled. If the mm-same-ip parameter is enabled, then mm-in-realm or mm-in-network can both be enabled.

To set the option that enables media release behind 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
   ORACLE(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.
