Ok. It seems to me that we're talking about two separate and distinct
things here:
* You want to scan for dialups to an external ISP(i.e. outgoing
calls)
* As far as I remember the person was talking about scanning a
the local PABX for modems that answered.
In the former case, you'd have to have cooperation from your local telco
people, either in-house and have all outgoing calls logged. In that case,
(and it's not an easy task), you'd call around to the local ISP's(don't
forget AOL, CIS, demon, etc.) get their local access numbers and check if
there are outgoing calls placed to those access numbers.
In the latter case(it's easier), you'd find a computer with a modem,
install something like Demon Dialer or another war dialer and just sweep
your company's "number space" of phone numbers.
Every time you found a Connect, log the number and go have a chat with the
owner of the offending equipment.
In general, I'd worry more about the latter case, since employees often
hook up modems, run a PPP server so that they can get access to the
Internet from home for free by piggybacking on your company's connection.
This tends to be what the modems are used for.
