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 restate, in this case the TELCO in not involved in polarity
switching, the ASTERISK port is connected to a Motorla VoIP Cable modem
(SBV5121) and I am reasonably confident that the Cable Modem is switching
polarity; I say this because I noted polarity switch messages in one of the
log files.

Perhaps we can clear this up, can you suggest what logging I can use and
where I should look so that we can refine the problem statement?

Regards Jonathan
