Video calls can be made using ARS. To make calls using ARS, video
systems simply dial the ARS dial-out code (usually
) followed by the
telephone number. The calls
must
be routed through ARS pools that have
only PRI, NI-1 BRI, and/or Switched 56 T1 data lines. To make a 2B data
call, the user must access two separate lines.
Barge-In Video calls cannot be barged into.
Call Waiting Call waiting does not work with video calls. The call appears to wait but
does not return to the extension when it becomes available. This feature
should be disabled at video system extensions.
Callback Video systems can be programmed for Callback. When either a pooled
line becomes available or the busy video system is idle, the queued call is
made, one B-channel at a time. When the second B-channel becomes
available, it is added to the call if the video system supports this capability.
Off-hook Callback must be used.
Automatic Callback should be disabled for videoconferencing extensions.
It can be used at an MLX passive-bus extension at a desktop video
workstation. If you use Automatic Callback, the call is connected as a 1B
data call.
Camp-On Video calls cannot be camped on.
Conference Conference does not function with video calls.
2B data video calls require both B-channels at a video workstation.
Coverage Individual Coverage is not recommended for 2B data calls. Because a
coverage receiver can have only one Cover button for each coverage
sender, covered 2B data calls are received only as 1B data calls at the
coverage receiver. The second call also continues to ring at the coverage
sender.
Coverage is not recommended for video extensions.
Directories Videoconferencing systems cannot make use of Extension, Personal, or
System Directories.
Do Not Disturb Do Not Disturb can be activated by video systems that have the ability to
dial strings and feature codes beginning with #.
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.
Last Number Dial Last Number Dial can be activated by video systems that can dial strings
and feature codes beginning with #.
