[Asterisk-Users] Asterisk and USB ISDN controllers ...

All I know about the adapter is what I've told you. It's a USB Colognechip
based ISDN controller - probably HCF-USB based. It's supported by Linux, but
there's no info on access to B and D channels.

Regards,
Hans

Since you don't mention what USB ISDN adapter specifically you are
thinking about, what do you think we will be able to tell you.

The first step would really be to ask if your specific ISDN adapter can
be used under linux. After that, can that specific ISDN adapter give
access to voice channels. What method is used to get access to the audio
and the signaling.

It may well be usable if the drivers for it implements the same API as
the current ISDN cards in use support.
