force telephone directory

first ask teh government to force telephone directory for landlines of tata and reliance.
its growing to dangerous propotions where unsolicited calls come from reliance,tata and airtel landline no’s through out the day and there is no way to track them down.
i feel its a pack between these private co’s and regu.atos to increase the sales of their fixedline phones over the bsnl, which is forced to maintain such a directory
