Media Release Behind the Same IP Address

The media management behind the same IP feature lets the Oracle® Enterprise Session Border Controller release media when two endpoints are behind the same IP address, in the same realm. Using this feature prevents the media for intra-site calls from going through the Oracle® Enterprise Session Border Controller. You can use this feature for both hosted NAT traversal (HNT) and non-HNT clients. It works with NATed endpoints and for non-NATed ones that are behind the same IP.

Additional Media Management Options

Additional media management options include:

Media directed between sources and destinations within this realm on this specific Oracle® Enterprise Session Border Controller. Media travels through the Oracle® Enterprise Session Border Controller rather than straight between the endpoints.
Media directed through the Oracle® Enterprise Session Border Controller between endpoints that are in different realms, but share the same subnet.
For SIP only, media released between multiple Oracle® Enterprise Session Border Controllers.
To enable SIP distributed media release, you must set the appropriate parameter in the realm configuration. You must also set the SIP options parameter to media-release with the appropriate header name and header parameter information. This option defines how the Oracle® Enterprise Session Border Controller encodes IPv4 address and port information for media streams described by, for example, SDP.

Configuring Media Release Behind the Same IP Address

You need to configure both the mm-in-realm and mm-same-ip parameters for the realm:

If the mm-in-realm parameter is disabled, the mm-same-ip parameter is ignored.
If the mm-in-realm parameter is enabled and the mm-same-ip parameter is disabled, media will be managed in the realm but released if the two endpoints are behind the same IP address.

To configure media management:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type media-manager and press Enter to access the media-related configurations.
```
ORACLE(configure)# media-manager
```
Type realm and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(media-manager)# realm-config
ORACLE(realm-config)#
```
From this point, you can configure realm parameters. To view all realm configuration parameters, enter a ? at the system prompt.
mm-in-realm—Enable if you plan to use mm-same-ip. If this parameter is disabled, the mm-same-ip parameter is ignored. If you set this to enabled and mm-same-ip to disabled, media is managed in the realm but released if the two endpoints are behind the same IP address. The default is disabled. The valid values are:
- enabled | disabled
mm-same-ip—Enable if you want media to go through this Oracle® Enterprise Session Border Controller, if mm-in-realm is enabled. When disabled, the media will not go through the Oracle® Enterprise Session Border Controller for endpoint that are behind the same IP. The default is enabled. The valid values are:
- enabled | disabled
