Perform FXO Port Tuning

Tuning the Foreign Exchange Office (FXO) ports can help the echo canceller to work more efficiently. The setup fxotune run command creates the fxotune configuration file, which contains the script that fine tunes the Digium Asterisk Hardware Device Interface (DAHDI) FXO channels, and restarts the system. The tuning takes place during the restart. After FXO tuning, the system saves the result in a configuration file that is automatically applied after each subsequent restart. No additional user action is necessary.

• Configure one or more FXO profiles and activate the configuration.

Note that the following procedure requires a system restart, which can take longer than usual due to the tuning process.

1. From the command line, type setup fxotune run.
2. Restart the ESBC.
