asterisk users - Mar 2005 - Asterisk and USB ISDN controllers ...

Guys,

I am planning on building a small SIP PBX with a single ISDN line. Currently
I am looking into the specs of a very tiny barebone system that has an
option Colognechip base ISDN controller. The only thing is that the ISDN
module that comes with this barebone hooks up to the motherboard using USB.
My intention is to allow incoming and outgoing calls from SIP to ISDN. Is
this setup in any way supported by *?

Regards,
Hans Vledder

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.

Hi Steve,

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
