Call monitoring involves a certain privileged user (e.g. a supervisor) tapping into a phone to monitor other extensions allowing being monitored. Yeastar IP-PBX has three monitoring mode:
Listen – you can only listen to the call but can’t talk.
Whisper – you can listen to and talk with the monitored extension without being heard by the other party.
Barge-in – you can talk with both parties.
Call monitor is a spy feature on Yeastar IP PBX. The ability to listen in a call without interference or join in the conversation as a third party is useful for a customer service or sales manager. Live call monitoring allows you to coach on the spot and guide the call so that there are no missed opportunities. Also, you can record calls and play them back later.
