Do Not Disturb
Do Not Disturb can be activated by video systems that have the ability to
dial strings and feature codes beginning with #.
A Do Not Disturb button should be programmed at MLX passive-bus
telephones, and the feature should be activated during 2B video calls.
Otherwise, voice calls ring and flash at the MLX telephone during 2B data
calls, even though they cannot be answered.
The use of Do Not Disturb at a passive-bus MLX telephone allows voice
calls to be covered while 2B video calls are in progress.
Forward and
Follow Me
Forward can be activated by video systems that have the ability to dial
strings and feature codes beginning with #. 2B data calls are forwarded
as two 1B data calls.
Remote Call Forwarding is not available at video system extensions.
Group Calling
When receiving calls through a calling group or data hunt group, video
systems can connect only using 1B data connections and only if the video
application supports 1B data. A calling group dispenses only one call to
each calling group member.
Hold
Video calls cannot be put on hold.
2B data video calls require both B-channels at a video workstation. For
this reason, if a call is on hold at a passive-bus MLX telephone when a 2B
call comes in, the passive-bus MLX telephone cannot retrieve the held
call until the 2B video call is over.
Last Number Dial
Last Number Dial can be activated by video systems that can dial strings
and feature codes beginning with #.
Messaging
Messaging features are not available for video extensions, but can be
used by MLX passive-bus telephones.
Multi-Function
Module
An MFM cannot be used with a digital communications device or
videoconferencing system.
Night Service
If a videoconferencing system is a member of the Night Service group,
voice calls to Night Service group do not ring at these extensions. Video
calls
do
ring, and 2B data calls can be established. However, if there are
two or more 2B data extensions in the system assigned to Night Service
groups, 2B data calls can be answered at the wrong extension during
Night Service.
Notify
Signaling can be activated by video systems that have the ability to dial
strings and feature codes beginning with #.
A Notify signal can be received at a passive-bus MLX telephone, even
when a 2B data or voice call is active.
Paging
Videoconferencing systems can be assigned to a paging group. However,
they should not be: they are not alerted if there is a call to a paging group,
and they cannot make group pages.
Park
Video calls cannot be parked.
