There *is* a way to do this, but I don't know the exact details. Basically,
the phone line (wire) has to show some bias (voltage) in order for the
modem equipment to recognize it as live. of course, won't see a dialtone,
will it ? Anyway, a guy at a company I used to work for worked up the
necessary hack using a phone cord and a 9v battery, so that he could test
our devices with modems without using the phone lines.
Perhaps try posting your query to the newsgroup comp.dcom.modems.
(and I'd be interested to hear the answer if you get one).
