Hi Steven,<br>
<br>
thanks for the reply :)<br>
<br>
So if I leave out the start_dtmf and start_dtmf_generate, the
send_dtmf will use RFC2833? This would be great.<br>
I have noticed that when running the example I sent in my original
email, that if I play a file before the send_dtmf that the dtmf gets
sent fine, but not playing a file will cause the dtmf to not be sent
:/<br>
I have put in a work around that plays a blank file, and that seems
to work, but could this be a bug?<br>
<br>
thanks<br>
Matt<br>

Hi,<br>
<br>
I have the need to send a dtmf tone, but send_dtmf does not
seem to work.<br>
I have the following in a dialplan, but doing a sip trace
the dtmf<br>
digits are not sent. I have tried removing the start_dtmf
and<br>
start_dtmf_generate, but still no joy.<br>
<br>
<action application="start_dtmf" /><br>
<action application="start_dtmf_generate"/><br>
<action application="answer"/><br>
<action application="sleep" data="2000"/><br>
<action application="send_dtmf"
data="0123456789ABCD*#@100"/><br>
<action application="sleep" data="2000"/><br>
