PABX or not, most teleco's will let you do call-diversion to another line or have some kind of answering service. If inbound calls never go to that line, you can be fairly confident that the modem won't be answering them. It shouldn't really be a problem in the first place; check that the modem isn't answering calls (by calling it) which is normally the default behaviour. If it is, switch the feature off and beat the errant user with a clue-by-four. Divert all incomming calls elsewhere just to be sure. Presumably outbound calls are direct to the legacy service and not using TCP/IP in any way (otherwise your user could presumably contact the same service via the internet) so shouldn't present any risk. One other thing to be aware of; there are a few 'dialler' programs out there that will phone Muldovia when you're not watching, any machine with a modem in it could be at risk. If your PABX allows it restrict outgoing calls on that extension as far as possible just in case.
