dtmf caller id
HI ALL,
I AM FROM INDIA. I WANTED TO DESIGN MY OWN CALLER ID BOX. I CONSULTED MY TELEHONE SERVICE PROVIDER, WHO GAVE ME A HINT THAT HE IS USING DTMF CALLER ID SYSTEM. I DESIGNED A DTMF DECODER FOR DECODING THE CALLER ID DETAILS. BUT FOR SOME REASON IT IS NOT RESPONDING.BUT THE SAME DECODER CKT WORKS WELL WHEN I DIAL FROM MY TELPHONE. :?:
I AM NOT SURE ABOUT THE DTMF CALLER ID PROTOCOL. CAN ANY HELP ME IN EDUCATING BOUT DTMF PROTOCOL.
REGARDS,
KUMARA
