God bless Pakistan, where you can get away with murder in broad daylight for just under Rs 1 lakh
i'm sure there are devices in the market to record calls
i've got an old phone in my junk which can record calls on to a cassette tape, but dont know if it still works or not
the simplest way i can think of right now is that if your phone set contains a jack for connecting headphones, plug a cable with male pins on both ends into it, plug the other end of the cable into either your computer or stereo system's microphone jack (red hole) or line-in jack.
waisay....
hai kaun ?

aisi kya khaas baat hai uss kay kalaam mein, jo record karnay ki zaroorat darpesh hogayi hain ?
