General
A station that has Trunk Queuing set is notified via internal ringing tone
if the station is idle, and the queued outside line becomes free.
Multiline Terminals with an LCD receive the message LINE IDLE when
the outside line becomes free. The Multiline Terminal user goes off-
hook to receive outside line dial tone.
Incoming ringing calls have priority over CO/PBX line queuing.
If two or more stations are queued to the same outside line, Trunk
Group, or Route Advance Block, a ringing tone is sent to the Multiline
Terminals in the order set, indicating that the queued outside line is
now free.
