The listen feature allows the operator to listen in on a call in which they are not
involved. To listen to call, select the local extension involved in the call (notice again,
the blue outline) and then click the “Listen” feature button.
[Figure 127: Select the active call, then click “Listen”]
After clicking “Listen” the operators extension will ring, and on answer will play the
audio of the selected call. The operator extension is muted and neither party of the
call is informed of the operator listening.
