Session Agent

Session agent RFC 2833 mode configurations override those on the signaling interface where they exit. The none parameter is used to defer to the signaling interface.

To configure the RFC 2833 mode on a session agent:

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 session-agent and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# session-agent
ORACLE(session-agent)#
```
Select the session agent where you want this feature.
```
ORACLE(session-agent)# select 1
```
rfc2833-mode—Set this parameter to either none, transparent, preferred, or dual based upon the behavior your want for this SIP interface.
- none—defaults to the behavior of the SIP interface for traffic that matches this session agent.
- transparent—does not add RFC 2833 telephone-event into SDP if not present, and does not prefer.
- preferred—adds RFC 2833 telephone-event media type into SDP and prefers to use this method for DTMF indication.
- dual—adds RFC 2833 telephone-event media type into SDP and sends both SDP and signaling-based DTMF indications if possible.
rfc2833-payload—Set this parameter to the media-type value you wish to use when inserting RFC 2833 telephone-events into an SDP offer. 101 is the generally accepted media type for RFC 2833 telephone-events.
