[Asterisk-Users] UK ISDN2e with DDI?

[Dogers]

We're about ready to go ahead with a nice 6 line (maybe later 8) ISDN setup with
Asterisk at Home and the quad Junghanns card.

Before we do, could anyone confirm for me that BT's ISDN2e lines do actually
provide Asterisk with the DDI number? We need to be able to route incoming
calls based on which number is ringing.

As an aside, has anyone actually managed to get the UK ringtones working
properly?? We've got Grandstream 2000's and they will only give us the US
ringtones!

Thanks,
Andrew
