Description
Extension Monitor – Telephone Line Monitor
A telephone-line monitoring device with an earpiece for authorized monitoring on a compatible telephone system.
The Extension Monitor is a telephone-line listening accessory for authorized monitoring on a compatible telephone system. It connects through a telephone jack and uses an earpiece to let the listener hear both sides of a conversation in real time. Its line-monitoring design is intended to reduce the connection effects associated with picking up an ordinary extension handset.
Real-time listening
The supplied earpiece provides live audio from both sides of a conversation on a compatible line.
Telephone-jack connection
The device is intended to connect through a telephone jack. Compatibility must be assessed for the actual telephone system rather than assumed from the presence of a connector.
Reduced connection effects
The design is intended to reduce the usual receiver-connection clicks, volume changes, and voltage changes associated with a conventional extension pickup. This is not a guarantee of undetectability.
Earpiece supplied
A listening earpiece is included, keeping the basic monitoring function focused on live listening rather than a speakerphone-style experience.
