Either that or have them hit the mute button and wait several seconds. Hopefully silence still works. :P You can even use sox to post-process and remove trailing silence from the recording.

It will just the funny application which will allow customers to record his changed voice which will sounds like Darth Vader for example:)  and to send to the destination number. It is easy but I can not create method for stop of recording from user side by means of DTMF because they is inband and 'soundtouch' modifies dtmf as well.
Yep you are correct. 'tone_detect' looks like nasty hackiness in this case but probably I will have to create this.

Question: what is the application here? Are you modifying the user's voice? It sounds to me like you are stuck. I suppose you could run the audio of a DTMF key through sound touch and then open it in a spectrum analyzer to see what happens. If it's predictable then maybe you could detect the resulting tones with tone_detect, but that just reeks of nasty hackiness. A better solution would be a carrier who can deliver 2833 DTMFs.

Unfortunately not. My inbound carrier can not do this.May be I will able to detect '#' which was changed by 'soundtouch' by means of 'tone_detect'.http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect

But not sure. This looks not good.

Do you have a way to send DTMFs via 2833 or SIP INFO?

bribge + loopback doesn't work because I have to set  <action application="set" data="playback_terminators=#"/>  ON B-LEG which is affected by  soundtouch.

Hm... Any ideas ?

Peter, yes I have "start_dtmf" and I can  detect DTMF. But! DTMF is not being recognised if I use <action application="soundtouch" data="0.7o 0.99t"/>I think soundtouch module changes my dtmf tones (which is inband).

I start thinking about bribge + loopback. This way I will able to use soundtouch on b-leg only.
Thanks.
