Hello Grant,

Been battling with our NetJet ISDN card and whilst it handles everything
voice quite well the most I've gotten out of a fax is about 50mm of normal
readable page followed by garbage. That's with mISDN, chan_misdn,
asterisk, iaxmodem, spandsp and hylafax. I couldn't seem to get
capi4hylafax working for it. Traverse tells me not to bother, the current
software DSP's just don't work well enough and the card has no DSP.

If anyone out there has SOMETHING which we could buy,beg,borrow or steal
by Thursday 12th of July 2007 that'll co-exist with our existing ISDN card
on the S-bus that can receive faxes I'll be most appreciative of it. Or
tell me what to buy ;-)

Currently it looks like avmfritz and hfcpci cards might be the go.


Unfortunately mISDN is generally a pretty poor quality piece of code,
and faxing in general is dodgy under Asterisk.

My best suggestion would be to use Bristuff instead of mISDN, and try either
of these combos:

* Bristuff + Spandsp (no idea if this will compile)
* Bristuff + iaxmodem + hylafax

Bristuff is a patchset (the author refers to it as a "spoon") to Asterisk,
Zaptel and Libpri. The advantage is it allows you to access your channels
in a Zap-like manner and is much less buggy than mISDN (no bri software
is that terrific though imho).

Not sure if the netjet even has a driver for Bristuff or not, something
to look into obviously. If you want to give Bristuff a go, download the
latest version from www.junghanns.net/downloads/ and extract the tarball,
inside is a script that grabs the correct copies of Asterisk, Libpri
and Zaptel, patches, compiles and installs them. You may need to fiddle
around manually to get spandsp in the picture.

I have an older Bri card sitting around if you may need it, not sure if it's
Bristuff supported though.

OK sounds like I should look into bristuff.

anyway, hope this helps, worst comes to worst you could divert the isdn line.

Umm how do I divert just ONE number out of the hundred group on our ISDN line? Telstra say they can't do it - it's ALL or NOTHING. Is there a way to deflect the call to another number (possibly at our cost)?

In any case I have been searching ... and searching since my last post and it looks like a Netgear RT328-S router is probably going to do the trick for now. I can plug our existing Analogue fax modem into it and according to the manuals I can set the number that it answers on. All I have to do is find one.. the blasted one on E-bay has the wrong interface :-(
