Configuring the SIP Interface

To configure a SIP interface:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the system-level configuration elements.
```
ORACLE(configure)# session-router
```
Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# sip-interface
ORACLE(sip-interface)#
```
From this point, you can configure SIP interface parameters. To view all sip-interface parameters, enter a ? at the system prompt.
If configuring an existing interface, enter the select command to select the interface.
options—Enter early-media-sdp-realms as the option. If adding to an existing list of options, use a preceding plus (+) sign.
```
options +early-media-sdp-realms
```

Continue to the next section to configure the outbound realm.

For example:

ORACLE(session-router)# sip-interface
ORACLE(sip-interface)# options + early-media-sdp-realms
ORACLE(sip-interface)# done
