FAX detection is not done in DAHDI, it's done in chan_dahdi (in Asterisk). CED detection is done in the echo canceler itself, so it is completely independent of Asterisk (or any application, for that matter). Correctly responding to CED is something that an echo canceler must do just to be compliant with various specifications. > Unfortunatly my Linux Machine seems not to log messages from DAHDI. > I have looked into /var/log/kern.log > There are messages from the kernel module like; > Feb 11 17:38:12 officepbx kernel: wcte1xxp: Setting yellow alarm > Feb 11 17:38:21 officepbx kernel: wcte1xxp: Clearing yellow alarm > > But no messages about echo can.

It's logged as a LOG_NOTICE message and is always generated, unless DAHDI was built with NO_ECHOCAN_DISABLE defined, which would be uncommon. However, /var/log/kern.log on your system might be only from the boot process. Have you checked 'dmesg' as the system is running? -- Kevin P.
