What is Monitor Barge?

Monitoring Barge is a phone system feature which enables you to listen into your colleagues calls with or without the incoming caller being aware. For example:

Joe Blogs calls Sarah. Sarah answers and starts to deal with the call. Sarah could signal for her supervisor, Paul when she starts to feel stuck. Paul can use the call monitoring barge to listen to the call whilst Sarah is on the call. He can advise Sarah on how to deal with at call, real-time, without Joe being aware.

The is an ideal phone system feature for those who need to train people on the phone such as call centres and customer service departments.
