We have two phone numbers (a local and and 800) which our clients use
to dial-up our computer.  We have n lines connected to n modems on the
local line, and m lines connected to m modems on the 800 line.  (Both
the local and the 800 roll to the next number when busy.)

Of course, sometimes all n local lines are busy, and 0 of the 800
lines are busy or vice versa.

Is there a device which allows one to connect two phone lines to a
single modem (or single-line telephone, for that matter) such that
when one line rings, the other line is busied out, and the ringing
line is connected through to the device?  Is there a better way?

(Our 800 is provided as a channel on a T1 from AT&T, and our local
number is just an extension on our PBX.  What I wish we had, but do
not think we can get, is a deal where the 800 number rings on our
local extension.)
