Debugging FXS Signaling
Overview: FXS debug monitors
Verify an incoming call
Make sure an incoming call is entering correctly context CS. In this example, a POTS terminal connected to
an FXS port goes off hook and places a call. The port is bound to a context CS interface named PHONE. The
debug output below shows a normal (working) call setup sequence.
