The Extension Monitor is a
discreet real-time telephone line monitoring device which works via any
phone jack on the system. Unlike monitoring using a regular telephone, this
device is transparent on the line; there are no clicks, volume decreases, or
voltage drops as would occur if a telephone was used for this purpose. The
user can silently monitor both sides of the telephone conversation through
the unit's ear piece.
Warning:
this product is to be used only in a legal and lawful manner in compliance
with all applicable laws and FCC regulations. |
