I'll try again using my subscribed address... Apologies to the moderators...

Hi All,

I've successfully got SIP and IAX2 working on Asterisk using X-Lite as a
  SIP phone and talking to a remote Asterisk over IAX2 using G729.

I'm now trying to get an ISDN BRI connection working. I have a Traverse
NetJet card (http://www.traverse.com.au/) which I currently have working
with isdn4linux (that's how I'm connecting to the Net).

I found the a message in the archives
(http://www.mail-archive.com/asterisk-users@lists.digium.com/msg32072.html)
that says audio support is needed in the hisax driver for it to work. I
have this morning downloaded and compiled 2.4.26, making sure that the
audio option was turned on, but I still don't get any audio (either
transmitted or received).

Is there anything else I should be looking at? Eg, does it depend on the
card version or perhaps a bios upgrade on the card?

TIA
Darryl
