Setting a Preferred Codec for a Realm

To set a preferred codec for a realm configuration:

These instructions assume that you want to add this feature to a realm that has already been configured.

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```

Type media-manager and press Enter.

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

Type realm-config 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)#
```

Select the realm where you want to apply this feature.

ORACLE(realm-config)# select
identifier:
1: public     media2:0         0.0.0.0
2: private    media1:0         0.0.0.0
selection:1
ORACLE(realm-config)#

options—Set the options parameter by typing options, a Space, the option name preceded by a plus sign (+) (preferred-codec=X), and then press Enter. X is the codec that you want to set as the preferred codec.
```
ORACLE(realm-config)# options +preferred-codec=PCMU
```
If you type options preferred-codec=X, you will overwrite any previously configured options. In order to append the new option to the realm-config’s options list, you must prepend the new option with a plus sign as shown in the previous example.
Save and activate your configuration.
