I have echo problems on my FXO modules and I've tried the different +echo cancellation algorithms in zconfig.h, tried tweaking the gains, and +still nothing works. What can I do? + +A. Use the fxotune utility. + +To use: +Just run the fxotune utility with the -i option. (`fxotune -i`) It should +discover which zap channels are FXO modules and tune them accordingly. Be warned +however, it takes a significant amount of time for EACH module to test, I would +say somewhere around 2-3 minutes. But you only have to initialize it once for +the line. It will write a configuration file to /etc/fxotune.conf. You will +need to have your system run fxotune with the -s flag (`fxotune -s`) to set the +module with the previously discovered values from fxotune.conf for it to take +affect, so essentially if each time you reboot the machine you need to run +`fxotune -s`. You might consider putting it in your startup scripts some time +after the module loads and before asterisk runs. + +As always, if you have any questions, you can email me at creslin@NOSPAMdigium.com + +Matthew Fredrickson |
