I play sound files using the AMI to originate a call to an extension that does chanspy on one leg and a playback on the other. I use channel variables to say which channel to play to and which sound file to play. SendDTMF or Playtones should be able to inject tones.<br><div>

Going foward, is there any way to programmatically inject DTMF tones into an already-bridged channel?<br>
</snip><br>
<br>
Well, due to the lack of responses, either I missed something obvious or nobody cares. I'm really hoping I didn't miss something obvious... :).<br>
<br>
In any event, I got curious of my own old question and hacked out a work around:<br>
<br>
0. Assume your extension is dumped into context 'mycontext'<br>
1. You dial an internal extension<br>
2. * Dials an external number (presumably another PBX device)<br>
3. When the remote device answers, both parties are dumped into the DTMFworkaround context<br>
4. The called party has its DTMF mode set to inband so that the tones are played out loud<br>
4.5. Meanwhile, the calling party is dumped into an empty meeting conference that is used soley to bridge these two legs<br>
5. When the tones are done, the called party is dumped into the bridged conference.<br>
6. When the caller hangs up, the conference boots the callee<br>
