In the UK but ... Cheap BRI card...

Whether it will work with asterisk is another matter though.
And what it has (or rather doesn't have!) when compared to those that cost
£100s is an intersting question, but I'm suspecting it's something along
the lines of the "soft modem" equivalent - ie. it's doing a lot more in
software to simplfy the hardware which may mean more CPU overheard.
But saying that, I once used a cheap ISDN card for over a year on a data
connection in a linux box (used the ISDN4Linux drivers in the kernel) and
it "just worked" and didn't notice any additional CPU overheard.

Well, at the time, there was pretty much nothing that was considered to be
"reliably" supported by Asterisk for NA BRI.
I picked up an Adtran Atlas 550 with a 4BRI-U interface and an octal FXS,
and I use the unit's built-in T1 network port to connect to an Asterisk
box. This works nicely, except for the things for which it doesn't work
nicely. The box is fundamentally being used as a BRI<->PRI translator,
but gives me some neat extras. .....
Has anyone else seen a working hardware solution that didn't cost an arm and
a leg? It seems to me that a BRI card should cost less than $100. I think
I remember a German friend telling me that they go for around $40 dollars.
I know that I can get a BRI with voice service out of Bell. I think they
have to provide it because of the CRTC tariffs.
The thing that has stopped me from trying it in the past is the uncertainty
around hardware. Do I understand correctly that NA (North American?) BRI is
different from the European version and that European hardware won't work?
If I could get a card for a few hundred bucks then I'd be willing to give
this a shot. Unfortunately, I can't afford a few grand for the Adtran setup
described, although it does sound cool and the BRI<->PRI conversion approach
is a clever way of overcoming the hardware scarcity.
For the number of times that I see people trying to get digital style
features out of analog lines, and banging their head against the wall, I'd
love to get a BRI working and be able to tell you all how it worked out.
