Summary:                    DAHDI/TDM410P does not detect ANSWER
Description: 
Outgoing calls to the POT's via DAHDI and a TDM410P do not detect the
remote party ANSWER.  The call is generated using a .cal file (attached)
and the call is never dispatched to the internal extension as expected.

A review of the RAW audio file (dahdi_monitor) shows that the call was
connected.

which DAHDI version? DAHDI does the polarity reversal detection.

Using a phone connected to your FXS ports do normal outgoing calls get
answered?

I see your config has 'answeronpolarityswitch=yes' and
'hanguponpolarityswitch=yes', which requires the telco to switch polarity
on each of these events, you didn't mention that you have confirmed this,
whether you subscribe to them, and that indeed that they do reverse.
