[asterisk-users] Debugging "stuck" inbound call

[Mitch Claborn]

Asterisk 11.1.0 running on Ubuntu 12.04 64 bit
Dahdi
Digium T1 card

Occasionally, I will find an inbound call that just seems to be stuck, 
usually in our after-hours menu portion of the dial plan.

This morning I had this one

core show channels concise
DAHDI/i1/5184097869-1baf2!MainMenu!s!20!Up!BackGround!custom/aa-night-hello&custom/hours_8:0-17:0_0:0-0:0_0:0-0:0&custom/aa-night-instructions!5184097869!!!3!9393!(None)!sip1-1396004671.285644

which had been there for about 2.5 hours (time from core show channels 
verbose).

The inbound channel here is to our toll free number on the T1.

When we've researched these in the past, we've not found a 
correspondingly long call on the phone bill, leading me to wonder if the 
call is actually being disconnected, but Asterisk just doesn't find out.

How can I go about debugging this?  Are the dahdi commands that can show 
me the connection status from the hardware perspective?
