[asterisk-users] TDM410P - False Answer Supervision

Since POTS supervision is questionable at best, the best option IMO would be
to use something like ForkCDR to let you know that the call has really been
answered.  Just do the ForkCDR on the polarity reversal.  This will give you
two CDR events for a good call and one for a bad call.
