[asterisk-users] Hang up detection with TDM400P and Telewest/Virgin Media line

[robb]

I have a TDM400 working quite well, Digium dialled in and recompiled   
chan_zap with some changes , to get BT Callerid working and  I have set 
hangup on polarity in the zaptel.conf which seems to work well

this is a BT home line, not business, if you have a business line you 
should get the DCT set to 800ms and the disconnect clear should work
