Because I wan't to be sure, that I have sent all dtmfs before releasing call. I think that ESL_EVENT_CHANNEL_EXECUTE can return before sending dtmfs, but ESL_EVENT_CHANNEL_EXECUTE_COMPLETE should return *after* sending dtmfs (*complete*).

Why do you need to know exactly when the DTMF was sent? Can you describe your use case?

Hello,
In my simple C application I want to send dtmfs. This is quite easy - you just call esl_execute("send_dtmf", "1234", uuid); and it works. However, ESL returns ESL_EVENT_CHANNEL_EXECUTE_COMPLETE way to fast - even before it starts dtmfs generation!
How can I know, when dtmfs were really generated? So far, the only method is to issue some sleep(), but it looks like big workaround.
