Description
Limits the amount of time that a call can be on hold
before reverting back to the phone that put the call
on hold and alerting the user.
Reverting calls are distinguished from incoming
calls by a single ring (or beep, depending on the
new call indicator setting for the line). This
notification repeats at intervals if not resumed.
A call that triggers Hold Reversion also displays
an animated icon in the call bubble.
You can configure call focus priority to favor
incoming or reverting calls.
Enables phones with a shared line to distinguish
between the local and remote lines that placed a
call on hold.
Allows the user to move a connected call from an
active state to a held state.
Enhances the file download process to the phone
to use HTTP by default. If the HTTP download
fails, the phone reverts to using the TFTP download.
The Jitter Buffer feature handles jitter from 10
milliseconds (ms) to 1000 ms for both audio and
video streams.
Enhances the audio coverage area by using a daisy
cable to connect two conference phone Sound Base
units.
When linked, voice, dial tone, ringer and base LED
features are synchronized between the two devices.
Allows users to notify the system administrator
about suspicious calls that are received.
