Great, that was exactly what I was looking for.

I was using uuid_record, not the ‘record’ app. I replaced it with ‘execute record params’ and now I receive a RECORD_STOP event. I think I can move forward with this small change.

Thanks a lot Michael!

What are you using to do the recording of the audio? The record app has built-in silence detection. If you are using record_session then I can see your dilemma. It's almost as if you'd need "execute_on_silence" as opposed to wait_for_silence.

Anyone out there have any suggestions for Hector on how to do this?

Hi,

I’m trying to use the wait_for_silence application to stop recording audio from a channel, and I need to use it not from a FS dialplan but from an ESL application.

So far I can execute the wait_for_silence application using ‘execute wait_for_silence arguments’ with no issues. I can even see the result of the execution of this command on the fs_cli console:

2012-01-05 19:04:40.266001 [DEBUG] switch_ivr.c:576 sofia/internal/5512@192.168.8.11 Command Execute wait_for_silence(200 15 15 5000)

EXECUTE sofia/internal/5512@192.168.8.11 wait_for_silence(200 15 15 5000)

The problem is that I don’t know if this is working or not, as it is not raising any event that can be received by the application. I don’t see any event related to this application (or to detect silence using any other mechanism) on the wiki Events List page [http://wiki.freeswitch.org/wiki/Event_list], so I’m not sure it is usable in an socket outbound mode.

Resuming: is it possible to detect the silence on a channel and then perform an action in an ESL application, using wait_for_silence app or any other mechanism?

Thanks,

Hector
