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.
See the Cisco Unified Communications Manager Features and Services Guide, "Hold
Reversion" chapter.
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.
• No configuration required unless you want to use Music On Hold. See "Music On Hold"
