Genoa SIR test probe, http://www.countersys.com/products/sirprobe.html
I can produce logs, hardware and time permitting, if anybody requires them,
but I'll leave the analysis up to you ;-)

Yes, this is a known problem that a (Psion-side) fix has been made available
for, because the Mot L7089 doesn't support this command.

The decoding looked pretty good. I'll check with a colleague tomorrow about
the sw versions (it was his phone I tested against, and I know he had
problems with some older software).

I presume you do mean analog fax & modem here.
I do know that international carriers often passively check channel content,
to avoid over-compressing delicate fax & data calls, while aggressively
compressing voice calls. Perhaps your network is doing something like this
too.
But anyway, my experience (with Orange) was that "analog" data calls worked
fine, but to connect to the Demon ISDN number I needed (free) data-enabling
of my account -- which also got me extra incoming fax & data numbers.
cheers,
