Messaging Messaging features are not available for video extensions.
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 #.
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.
Personal Lines Personal lines can be assigned to videoconferencing systems. It is best
for these extensions to have exclusive use of their own personal lines; if
they do not, the system manager should ensure that enough idle lines are
available, particularly when a video system is receiving 2B data calls.
Otherwise, the video system may receive only 1B data while another
extension is using a second personal line.
Pickup Pickup is not recommended at video system extensions.
Pools If a videoconferencing system is programmed to have a single Pool
button, two calls to that pool result in a 1B data call. However, if two
separate pools are assigned to a videoconferencing system extension,
then a 2B data call can be established. If a system includes two or more
video systems sharing the same pools, incoming 2B data calls can be
misrouted.
Privacy Privacy is activated automatically for video calls.
Reminder Service Videoconferencing systems cannot receive reminder calls.
Remote Access Video calls cannot be made into lines programmed for remote access.
Ringing Options Personalized Ringing and ringing options have no effect on calls to a
videoconferencing system.
Speed Dial Speed Dial codes can be used only on digital video systems that have the
ability to dial feature codes or number strings beginning with
.
Tandem Switching In Release 6.0 and later systems (Hybrid/PBX mode), when tandem PRI
trunks connect networked systems, these systems can perform data
transfers at speeds up to 128 kbps (2B data). Tandem T1-emulated tie
trunks programmed for data can perform data transfers at speeds up to
112 kbps (2B data).
Transfer 2B data video calls require both B-channels at a video workstation.
