1. you need oen the reverse polarity signal to detect otherside answer of hangup.
after you open reverse polarity signal from the provider. edit the /etc/asterisk/chan_dahdi.conf
answeronpolarityswitch=yes
hanguponpolarityswitch=yes
and command the busydetect and busycount parameter.

loadzone=uk
defaultzone=uk
usecallerid=yes
ukcallerid=yes
cidsignalling=v23 ; Added for UK CLI detection
cidstart=polarity ; Added for UK CLI detection

1. if you have reverse polarity signal for answer and hangup, you should command busydetect and busycount parameter.
2. you mean same pstn line before work well on same card but recently can't detect remote answer signal?
3. you can add my skype:dario.hu2 and prepare teamvidw for check.
