Call logging (also known as call recording or call monitoring) is the practice of listening to, recording and assessing interactions between call center agents and callers. These practice is used for staff training and development, customer quality control and liability protection.
Construction: Solder all the parts provided in the kit properly. First connect the jumper wires(links) before you solder the ic sockets. Donot solder ics directly on the circuit board , it may damage the ic since you my not be experianced soldering person. So solder the ic sockets first on the circuit board. Solder smaller components first like resistance and disk capacitors, assemble the complete kit one by one. Please make sure that there are no short circuits left on to the circuit board. The is operated by 9V battery. Now connect the battery to the connector provided, and plug to the the socket connected the circuit board. Check the voltage at the output of the regulator. It should be perfactly 5v dc. Small power indication led will LD1 will also come on .Check the voltage at the power supply pins of all the sockets mounted on circuit board it should be 5v dc. c. Now if all the voltages are ok then place all the ics in their sockets , Now connect the telephone line to the telephone connector k1 and
other end to the parallel line of the telephone socket..After telephone line is connected there should be 52v to 55v dc on to telephone line. Connect RS 232 cable to one end of the circuit board and other end to the pc.. Switch on the power supply to the device.
