Open the headset carefully. It can be easily opened. Two wires will be coming from the pin side. Check the continuity with the two connections and pin steps. The edge will be +ve. or else you can see M+ and GND or M- on the small PCB. Just solder the two wires at the already soldered connections. hope this helps you.!!

if you still have connecting your headset. mail me at arifuddin2007@gmail.com

2009-12-21T22:51:08.545-08:00

To 'a half light':
When you dial a number, the DTMF codes of the keys you press go upto exchange only, they don't go to the person you are dialling.
After exchange receives the number which you are dialling, it sends your number to the dialled persons telephone using DTMF codes (ofcourse exchange knows your number whenever you make a call, they've to bill you after all!!)

to 'abhi...nav':
I've not tried online shops for DTMF decoder, but I get it in Chennai Ritchie Street market. I've also got some of them earlier from Ahmedabad and Mumbai (Grant Road) electronics markets. So, if you are near any of these places, you can just buy them directly from the shops.

2009-12-10T07:09:48.574-08:00

Hello,
can you please tell me how the dtmf system transfers the CALLER'S number? I mean, i know the basics, i just don't get one thing (it might be a very foolish question): If i'm the person dialing, then i'll dial a number, then if that number is getting displayed at the other end, it effectively means the person i'm calling is seeing his own number; (i'm 100% sure that's not the case but i just can't see how the caller's number gets displayed at the other end instead of the number of the person himself!)
Please enlighten.
