<div dir="ltr">Why do you need to know exactly when the DTMF was sent?

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>Hello,<br><br></div>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!<br>
</div><br>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.</div>
