OK, I suspected that was what you meant but wondered if I'd missed an option
somewhere.

As far as I can see (and in fact this is still unfamiliar territory for me)
a. the options you get when you use e.g. File|"Send a fax" in Fax console
to send a single fax are /probably/ just applied to that single fax. That
option simply seems to build a complete dialling string - in my case, e.g.
+44 (0161) xxx xxxx.
b. I couldn't find any option that allows you to apply the dialling rules
to all faxes sent via the fax service.
c. the fax service documentation suggests that if the faxnumber you provide
to the macro contains a canonical fax number, then any outbound /routing/
rules will be applied. However, my understanding is that those rules are
really about selecting which device to use, rather than about how to
construct a diallable phone number with, e.g. long distance prefix where
necessary.

So the only thing I can suggest is that if you are not starting with numbers
in canonical format, you try that to see if it makes any difference (FWIW
whenever I try to create rules here, the MS software appears to construct a
number that does not actually conform to UK dialling conventions, which
suggests that either I am doing something wrong or that the software is. But
it certainly makes it impossible to test anything in this area).

e.g. if the number is in the US, try using

+1 (aaa) 555-1234

where aaa is the area code, rather than just e.g. aaa5551234 or whatever you
actually have at the moment.

code to be prefixed to the phone number. The fax console allows an option to
use these rules when sending a single fax, so I was wondering if this option
could be specified at the moment of the fax send in the macro. Hope this is
clearer.
