Hi,<br>
<br>
Mine was a combination of things. One problem seemed to be as I
described in an earlier post, that something (dahdi?) was not happy
if I disconnected the trunk lines. This manifested as the dtmf
problem and echo cancelling problem (and "cat /proc/dahdi/1" would
show oslec as INACTIVE). Even after figuring out that shutting down
the machine and restarting helped, I still had an occasional echo
problem even though "cat /prod/dahdi/1" showed that oslec was
active. I eventually fixed that by increasing the taps to 128 in
zt.conf.<br>
<br>
As you can no doubt tell from my posts, I am a relative noob to
freeswitch, but these are things which worked for me. I did a
previous installation which was sip only (no analog card), and that
was much easier!<br>
<br>
Best,<br>
Tim<br>

<pre wrap="">Hello List,
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?

It seems that explains. But I not sure.
