block unwanted calls on airtel

• Actually this is not a trick bt a service.
• but wid a simple freak u can use it for free. 
• We have also realized that some ppl are irritating us by calling every time and you dont want that particular person or number to call u ever. Here is a simple way by which you can completely customize the incoming call that means which caller even which callee group you want to call you simply adding them into the blocked list. 

• So the name of the service is AIrTEl Call ManAGer..

•  LET ME TELL YOU VERY CLEARLY , DONT TRY THIS AT HIGH BALANCE or use USSD CODE(*323#). 

• The trick is go the below link 
• LINK:----- http://cm.airtel.in 

• then go to new user. Enter your number and press ok. 

• U'll get a password on your number. Now login using the credential and in the block list enter(s) the number of the caller separating by coma. Nd block them.u hv done it. Another thing u can customize there z whether you want the alerts for the rejected calls or nt. 
• PLEASE TRY AT ZERO BALANCE...
