I can tell you how I solved the problem I was having. Don't know if
this is preferred, or if there is a better way, but I'm now able to
detect dtmf from all sources (pstn, cell, sip).<br>
<br>
Apparently, mod spandsp has better dtmf detection than the dtmf
detection in the freeswitch core. On the wiki page for spandsp
(<a class="moz-txt-link-freetext" href="http://wiki.freeswitch.org/wiki/Mod_spandsp">http://wiki.freeswitch.org/wiki/Mod_spandsp</a>), there is a section on
dtmf. I added the spandsp_start_dtmf parameter before calling the
ivr, and that fixed my issue.<br>
<br>
Hope this helps,<br>

<pre wrap="">I have a freeswitch server with a digium tdm wildcard. Compiled,
enabled, and configured freetdm and dahdi...all seems to be working fine
(can make/receive calls).
My problem is with dtmf. When calling from an external pstn number to
freeswitch, dtmf seems to be detected properly and consistently. But
when calling from a cell phone or via another voip line, dtmf doesn't
seem to be detected, or detected only occasionally.
On the same system, if I call into the voip number, calls from any of
the three external options (landline, cell, sip) all seem to work fine
with dtmf.
So the problem seems to be something I've misconfigured with the tdm
card. Can anyone point me in the right direction?
