CALLER ID IN PANASONIC CORDLESS PHONE WITH ANSWERING

CALLER ID?

I AM IN BANGALORE, KARNATAKA STATE, INDIA. MY DAUAGHTER HAS RECENTLY GIFTED ME WITH A PANASONIC CORDLESS PHONE WITH ANSWERING MACHINE PURCHASED IN THE U.S. THE PHONE CONSISTS OF 1 BASE UNIT (WITH ANSWERING SYSTEM) AND 2 HAND SETS. MY TELEPHONE SERVICE PROVIDER IS BSNL, BANGALORE. THEY PROVIDE CALLER ID FACILITY AS A DEFAULT SERVICE NOW. YET I REQUESTED THEM TO SPECIFICALLY PROVIDE THE SERVICE AND AFTER CONFIRMING FROM THE EXCHANGE THEY INFORMED THAT THE SAME HAS BEEN PROVIDED. INSPITE OF THIS, I AM NOT GETTING CALLER ID IN MY CORDLESS PHONE. HOW CAN I GET IT? PLZ REPLY TO MY EMAIL ADDRESS gopu2002@yahoo.com or kovengo@rediffmail.com
