[asterisk-users] DISA and DTMF detection problem w/ FXO port on a TDM400

Sun Sep 16 22:28:27 CDT 2007

Hi,

It's probably an echo problem. Try to use fxotune (with new patch) for
determine echo levels.

Try change lines in FXO. For example, use an FXS in some loopback mode.

You can also try to set txgain= - 12  (minus 12) ... this will reduce the
dialtone and DISA will work.
Of course -12 dB will attenuate your sound so it's just a test.

Luis A P Barbosa.
