dont receive calls starting with 700

From January 2011, all telemarketers' mobile numbers wil start with the same three digits: 700. This means you will be able to identify a telemarketing call the moment the number starts flashing on your mobile screen. It's then up to you whether to cancel, ignore or take it. This is part of the

'Customer Call Preference Regulation' on curbing unsolicited marketing calls and SMS messages that the Telecom Regulatory Authority of India (TRAI) will announce on Tuesday.

The existing National Do Not Call (NDNC) directory will be replaced by a new regime under which subscribers will also  have the choice of getting telemarketing calls — if they want — from specific segments of the market for a time period decided by them.

For instance, if a subscriber is looking for a house and wants telemarketing calls from real estate agents for three months, he will get calls only from the real estate segment.

Currently, the NDNC directory maintains a database of all telephone numbers of subscribers who do not want to receive unsolicited commercial calls. A subscriber can register his telephone number with their telecom service provider for inclusion in the NDNC.
