Hi,

I am having a continuing problem with freeswitch and the Digium TDM card. For some period of time after a reboot, DTMF is detected correctly for incoming calls, and there is no problem with echo. All is good.

Then at some point, dtmf is no longer detected on incoming calls handled by the TDM card. Presumably at the same time that dtmf quits being detected, the echo cancellation quits working. Again, just on incoming calls handled by the Digium card. The only way I've been able to get things working again is to reboot the server, but it doesn't seem to last for long.

Can anyone suggest how I might track down what is wrong? Try enable DTMF debug in freetdm and compare results.

Example for freetdm.conf [general] debugdtmf_directory=/var/spool/freeswitch/dtmf [span zt mySpan] debugdtmf => yes -- WBR, Dubrovskiy Viacheslav
