When FreePBX reboots, I have horrible echo. I can run fxotune and then it is great until next boot.
When I run fxotune, I get lines like this in the output
Found best echo coefficients: 1=9,0,251,252,2,255,0,0,0
/etc/fxotune.conf shows a new modification time, but does NOT have the above settings in the file, it has
instead. I have manually put in the data from the fxotune run, but I wonder why fxotune does not write these numbers into the /etc/fxotune.conf file?
