0. About

Generate DTMF on current channel.

1. Usage

<action application="start_dtmf_generate"/>

2. Example

As an example, placing this in the dialplan prior to bridging a call will allow a phone set to rfc2833 OR info to send DTMF tones inband out to the recipient (IVR) or Auto Attendants. Thus changing the outgoing routing from info or rfc2833 to inband.

TODO RFC 2833 is obsoleted by RFC 4733.

3. Notes

This option WILL NOT WORK with bridge_early_media when used as so:

<action application="export" data="nolocal:execute_on_media=start_dtmf_generate"/>
<action application="set" data="bridge_early_media=true"/>
<action application="bridge" data="sofia/..."/>
