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.
