dahdi_monitor and busy detection


I can’t find any documentation for busy detection with dahdi_monitor.

There is information about dahdi_monitor parameters but i can’t find how to use recorded busy tone with asterisk.

Thank you,

Why would you be using dahdi_monitor for busy detection ???


I am searching a way for handling multiple busy tones for hung up detection
