Debugging FXS Signaling

Overview: FXS debug monitors

Command	Purpose
unit#debug ccfxs	Prints all operations on the FXS interfaces (high-
	level).
unit#debug fxs	Prints all operations on the FXS ports (low-level).
unit#debug media-gateway control	Prints the dialed digits.
unit#show call-control provider name	Shows the status of an FXS interface in context CS
[detail detail]	(call control part of FXS signaling). Shown are all
	calls currently ongoing on the interface, with their
	call states, signaling peers and voice data path
	parameters.
	name is the name of the FXS interface. Use detail 5
	for most verbose output.

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.
