[Asterisk-Users] UK ISDN with Asterisk

[Henry Owens]

John,

Thanks very much for the detailed response, that sounds pretty much like
what i'm looking for (1x BT ISDN2e and 1x analogue). Are you using one
of the Digium 4 port BRI cards, or what hardware are you using?

It would be my intention to use the ISDN primarily for incoming, and
VoIP for outgoing to cut costs, and increase functionality. You
mentioned your PSTN number is routed to you via IAX; can that number be
included in local directories?

I don't think the analogue CLI should be a problem, since the ISDN
should be taking most of the incoming calls. Does CLI work ok on the ISDN?

At this point i would intend to use only 1 ISDN card, so i'll cross the
multiple card bridge when (and if) i come to it.

Thanks again!
Henry.
