Realm

To configure SIP number normalization for a realm:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type media-manager and press Enter to access the media-level configuration elements.
```
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)#
```
You can either add SIP number normalization support to a new session agent configuration or to an existing session agent configuration:
- For a new realm configuration, add the option by typing options, a Space, and then number-normalization.
```
ORACLE(realm-config)# options number-normalization
```
- For an existing realm configuration without any options already configured, select the realm, type options followed by a Space, and then number-normalization.
```
ORACLE(realm-config)# select
ORACLE(realm-config)# options number-normalization
```
- For an existing realm configuration with other options, select the realm, type options followed by a Space, the plus sign (+), and the number-normalization option.
```
ORACLE(realm-config)# select
ORACLE(realm-config)# options +number-normalization
```
Save your work using the ACLI save or done command.
