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.

---------------------------------------------------------------------- 
Just to clarify... in many countries (the United States being the most
obvious one), the telco doesn't do *anything* to signal when the far-end
answers a call.  Zip.  Zero.  Nada.  Nothing.  

If you're lucky enough to be in a country where the telco reverses
polarity to signal that the far end has answered the call, then this is
most likely a bug.  I just don't want people's expectations to be set
inappropriately because of a misunderstanding.

Does that help clarify things?
