Bingo!

I had read the README.udev, but had not noticed any make-time udev 
related messages so chose to ignore its contents.

Bad, bad boy - naughty me.

Anyway, dumping those lines into the 50-udev-rules file has solved this 
issue perfectly. I can now modprobe zaptel then ztdummy with no errors 
and asterisk loads & opens all the IAX stuff & confirms that it is 
listening on port 4569.

Cool - well spotted.

Now to get rid of these darn issues:

I'm sure its now possibly a phone setup, but being green at this 
asterisk stuff, I let them sell me the phones without setup manuals or 
anything. grrrrrrr.

In response to the ethereal queries I was asked:
All PCs & phones on this network plug into the same 3com switch, port 8 
of this switch links to a netgear DG834 (my ADSL modem/router/firewall). 
The three remaining ports on the netgear are unused, but if I plug 
anything into them, the netgear DHCP offers them a compatible IP and 
they can see everything plugged into the 3COM. Note that *all* equipment 
that is permanently connected has a *fixed* IP and does not get one from 
the netgear DHCP service.
In short, the fact that ethereal saw nothing coming from the phones 
suggest a phone setup issue.

However

the fact that when I dial *1202 (*1 being the phones IAX dial-prefix), 
asterisk responds to the request, shows that the phones do however 
communicate in some recognisable way.

Maybe I should also fiddle with a minimum iax.conf and extensions.conf.

Chat soon & thanks,
Zoltan
