I dont know what's the big deal about it! If you are not interested, dont take the call. In a meeting, as far as my organisation is concerned (a govt one), cell phones are strictly required to be switched off. It's somebody's earning yaar, let them do it. Why you say it has made life "hell"? There are so many other things that make the life a real hell. Remember, by banning the telecalls legally, you will get yourself a call less daily but the talecallers will get a meal less or a dream less for that sake. Thank you.
