add "start_dtmf" app to your dialplan before bridge to start the inband dtmf detector.<br><br><br><div class="gmail_quote">On Tue, Dec 22, 2009 at 8:57 AM, Scott Torr <span dir="ltr"><<a href="mailto:scott.torr.fs@letterboxes.org">scott.torr.fs@letterboxes.org</a>></span> wrote:<br>

If I dial 501 from from a sip phone using "inband" dtmf I can see the<br>
dtmf tones being detected and decoded by fs in the debug log.<br>
<br>
<br>
If however I use a pstn phone and dial my skypeIN telephone number the<br>
call comes into fs via skypiax but when I generate dtmf tones on the<br>
phone they are not detected or decoded by fs.<br>
<br>
If I take the record_session file and spectrum analyze the recorded<br>
tones appear to be within spec.<br>
<br>
<br>
Can anybody suggest why this is not working for me?<br>
<br>
<br>
Is the correct sample rate being used in libteletone_detect.c?<br>
Does the Goertzel algorithm work for other sample rates other than<br>
8000hz?<br>
<br>
<br>
I'm not sure why I can not get this to work?<br>
<br>
<br>
