If you need to place and receive calls with the modem, use the setup shown in

available for users at other extensions when all other lines are busy.

Calls on the modem line (line A) ring only at extension X. Likewise, line A is the
Iast line selected by other extensions in the system, so the modem line is
unavailable for the modem only when all other lines in the system are being
used.
