I Applications
Videoconferencing
Outside Video Only. Only one SA button should be assigned to the
extension(s). To make a call, enter the line number (for example, 808) of
an outside line assigned to the adjunct extension; repeat this step for the
second call, using another assigned line number. Or, if ARS has been
programmed for data, enter the ARS access code (usually
the telephone number, for one of the calls.
To disconnect from a video call, follow the instructions provided with your
videoconferencing equipment.
Considerations and Constraints
Generally, video workstations should have exclusive use of their own lines and
dedicated pools (Hybrid/PBX mode only). Because they require two lines for
optimal performance, sharing lines is often not practical. Pools should be
assigned only lines that provide like services (for video systems, T1 data-only, or
PRI and BRI voice and data). ARS should also be programmed so that extensions
access pools with the proper grouped facilities (T1 or analog voice only, T1 data
only, or PRI/BRI voice and data). ARS default local and toll tables should be
programmed to route calls according to their type: voice only, data only, or both
voice and data. For more information,

When a passive-bus MLX telephone is included in a desktop video workstation, it
should be located near the video system, so that the user at the telephone is
aware of calls at the video system.
Feature Interactions
Features that redirect the destination of a call (for example, Coverage features
and Forwarding) are not often practical for extensions used by videoconferencing
systems (although passive-bus MLX extensions can take advantage of these
features). For example, if a video system is a coverage sender, a receiving video
system can be assigned only one Cover button for the sender. Therefore, it
cannot receive both calls of a 2B video call.
Data hunt groups are not practical where 2B data is required, because two calls
must arrive at the destination video system, and data hunt groups distribute the
two calls that make up a 2B data call to two different data hunt group members.
The following list details specific feature interactions. For additional information,
see the Data/Video Reference.
Account Code Entry
441.
Account Code Entry can be entered for calls made by video systems that
support the use of # for feature codes. The account code must be entered
before the telephone number.
