What device do you use? wcfxo has always reported this as RED alarm on
the span. The drivers of the Astribank also did so for quite some time.
In recent versions of Zaptel all the Digium analog cards' drivers do so
as well.

So a quick look at /proc/zaptel/1 will show you that the channel is RED
(yes, there are also channel alarms for that in latest Zaptel versions).

And then in Asterisk 'zap show channel 1' will show you that the channel
is "InAlarm". Hence it won't accept calls. Thus you can safely include
it in a group of channels. Maybe this is what you were after in the
first place.
