Features
Digital Data Calls
Transfer
Voice Announce to
Busy
Data calls cannot be transferred.
2B data video calls require both B-channels at a video workstation. For
this reason, if a call is on hold for transfer at a passive-bus MLX telephone
when a 2B call arrives, the passive-bus MLX telephone cannot retrieve
the held call until the 2B video call is over.
Voice Announce to Busy should be disabled at digital data workstations.
At a passive-bus MLX telephone, Voice Announce to Busy requires one
of the B-channels needed for a 2B video call and should be used only
when the video system is not active on, or receiving, a call.
