Call Chaperone Allows an authorized Chaperone user to supervise and
record a call.
The Call Chaperone user intercepts and answers the call
from calling party, manually creates a conference to the
called party, and remains on the conference to supervise
and record the call. Cisco Unified IP Phones that have the
Call Chaperone feature configured on them have a Record
softkey. The Call Chaperone user presses the Record
softkey to record a call.
For chaperoned calls, an announcement is played or
spoken by one of the participants at the start of the call.
An announcement later alerts participants in the call that
the call is being recorded.
The Call Chaperone feature is supported only with the
External Call Control feature, which allows Cisco Unified
Communications Manager to route audio and video calls
to a route server that hosts routing rules.
For more information, see the Cisco Unified
Communications Manager Features and
Services Guide, External Call Control.
