[asterisk-users] TDM400P FXO click sounds

[Michael Munger]

I have this exact same problem with two different Business Edition
systems. Both are using TDM400s. 

Do we have an answer for this yet?

As mentioned by Stephen, if the echo canceler is improperly tuning that 
certainly might be possible.  But moreover, if there is ambient line 
noise that is on the line, fxotune will try to pick the best settings on

the line interface to either mitigate any line noise that it receives in

the audio receive path.

One other possibility is you could see if it the clicking and popping 
correlates to hard drive activity... if that's so, you might have a hard

drive or raid controller disabling interrupts for too long.
