[asterisk-users] UK (BT) Problem with TDM 400P

[Mark Muffett]

I'm trying to get my TDM400P to work with a BT POT line.  I've done
everything I can think of to get the uk settings right (in
zapata.conf, zaptel.conf and options for the wctdm driver) - and they
all look right (ie uk like) and look like they are working when I try
diagnostics with lspci, dsmsg, asterisk -c etc - but when I connect
the FXO unit to the BT line it just makes it (the BT line) go
permanently engaged.  I'm tearing my hair out and about to chuck it
all in the bin, but before I do, has anyone ever managed to get a
TDM400P to work with a BT line and did they have any of these issues?

Thanks for any help

Mark
