To record voice data to pc sound card, insert a 600:600 ohm transformer in series with the telephone line. One coil in series with phone circuit, the other connected in parralel with two 4v7 zenner diodes anti-series (protection against ring voltage and other overvoltages) and to soundcard line in. Also, make sure you do this for legal purposes. Listening to what other people talk is not legal.

Hi gsmsikar,

You can record telephone conversations with good quality using a hardware interface like:

You can connect two lines to the soundcard, but you cannot record both at the same time (or they will be mixed together). This is a limitation of the soundcard hardware (you have only one CODEC per soundcard). There are some multiple soundcards, but they cost a lot!
You can try to install more than one card in your computer. Some models do work with this configuration and it's much cheaper

Hope it helps!

but how can i also get the caller id of the incoming phones which are recorded if i use 3 sound cards at the same time and record all the three voices at the same time?

Hi gsmsikar,

You need one hardware adapter for each line. The soundcard enables the recording. The callerID information comes through the serial port. In this case you would also need three COM ports available.

Hi gsmsikar,

Sorry for my late reply...

The hardware interface I suggested ( http://www.plusdesign.com.br/Recorder.htm ) has a serial interface (RS-232) through which the CallerId information is sent to the computer. The hook information also comes through the serial port, enabling the automatic recording of conversations when the phone comes off-hook. The interface also has an audio output that has to be connected to the line-in input of the soundcard. There is a phone jack to be connected to the telephone line (in parallel). The unit does not need to be near the telephone. You just need a parallel connection to the telephone line you want to record from.
The software has a manual and an automatic mode, it can run in a hidden state, and also has a real-time monitoring mode.

Regards

Use a Voice capable external modem (any dialup external modem) + a program called Advanced telephone recorder...it has got Caller id also..
