Group Calling
Personal lines can be assigned to terminal adapters and desktop video
systems, however the personal lines should not be shared between
them.
Personal lines can be shared between an MLX and a terminal adapter
connected to the MLX adjunct port. This configuration allows voice calls
to ring at the MLX telephone, and data calls to be received by the
terminal adapter.
Personal lines can be shared between an MLX, analog multiline
telephone, or single line telephone and a desktop video system in
standalone configuration. This setup allows voice calls to only alert at
the telephone, and data calls to be answered by the desktop video
system.
Personal lines can be shared between an MLX and a desktop video
system in passive bus configuration, however, only 1B Data calls can
be made to the desktop video system in this arrangement unless the
personal line on the MLX telephone is set to delayed ring or no ring. 2B
Data calls can be completed in this situation.
A Personal Directory (MLX-20L only) or System Directory can be used to
dial numbers on a personal line. An Extension Directory is used only for
inside calls and cannot be used to dial calls on a personal line.
A user cannot select a personal line and dial an outside number when
the number is on a Disallowed List assigned to the extension.
When Forced Account Code Entry is assigned to an extension and the
user tries to dial an outside call on a personal line button without
entering the account code, the call does not go through.
When an extension is programmed as the principal user of a personal
line, calls received on the personal line are forwarded to an outside
number (if the extension can use remote call forwarding), unless the
outside trunk is a loop-start trunk with unreliable disconnect.
If a person uses a shared personal line button to join a call in the calling
group queue, the call is removed from the queue. If a delay
announcement is playing, it is disconnected from the call.
To allow all calling group members' telephones to ring when an outside
call is not answered within three rings, the trunks programmed to ring
into the queue can also be assigned as personal lines on group
member telephones and programmed for Delay Ring. This does not
work for inside calls, remote access calls, DID calls, or when a delay
announcement device is assigned to the group.
