Summary:                    [patch] FXS Polarity Reversal on Hangup or Answer
Description: 
FXS lines normally connect to a telephone.  However, when FXS lines are
routed to an external PBX or Key System to act as "external" or "CO" lines,
it is extremely difficult, if not impossible for the external PBX to know
when the call has been disconnected without receiving a polarity reversal
on the line.

DAHDI/Asterisk should have a feature to allow a setting someplace, perhaps
in chan_dahdi.conf, to allow a FXS channel to provide a polarity reversal
on channel hangup.
