asterisk users - Jan 2004 - Voicetronix Openline 4 + asterisk

Any one has documented how-tos for making voicetronix openline 4 to work 
with Asterisk.

I have been contacting Australian Digium resellers and Digium cards are 
not approved in Australia. So I suppose Australian users are interested 
into putting Voicetronix in use.

Any expereience to share will be most appreciated.

The other approved option is AVM Fritz!Cards from the Australian Distributor
listed on AVM's site.  It's pretty cheap to convert a
POTS line to ISDN2 which allows two simultaneous calls, plus you get all the
niceties of digital call handling, echo cancelling etc. using chan_capi from
www.junghans.net.

The price should be slightly better than openline4s on a per line basis.

However, I think telstra won't let you have ADSL on an ISDN line, even
though it works in other countries, maybe there are no ISDN/ADSL modems
approved for Australia.  We have two ISDN2 lines giving us 4 voice lines,
and an ADSL/analogue line for Fax and Internet.

You can still use your analogue phones/modems etc with the ISDN2 lines
(Telstra gives you an "NT1 Plus II" which accepts analogue phones)

A trap is that if you plug a USB cable into the "NT1 Plus II", it
disables
the S-BUS which you need to connect to the AVM Fritz Card.

An even cheaper option is the Netjet card from traverse, but it uses
chan_modem_i4l which doesn't have any echo cancellation.

Cheers,
Woody
