To Use
Incoming calls on line 4 ring only at extension X. For outgoing calls, line 4 is
the last 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.
To Set Up
1.
Set Automatic Line Selection for extension X to select line 4 first; for all
other extensions set Automatic Line Selection to select line 4 last. That
way, the modem line is used for outgoing voice calls only when all other
lines are busy.
2.
Set Line Ringing for line 4 on extension X to Ring. Set all other lines assigned
to extension X to No Ring.
3.
Set Automatic Extension Privacy (#304) for extension X to Assigned.
4.
Set up the modem so it will answer incoming calls. Refer to the device’s
documentation for instructions.
