Sorry to intrude into this thread. I have a similar problem which I 
posted a couple of days back.

Is there a way for me to check if my network provides CPD, if indeed 
that is the problem?

I am now testing using internal pbx, but even when I connected to my 
BSNL network (In India), Zap was not detecting the remote line hanging up.

I would like to hear any one using Zap under BSNL in India.
