This App is available from the Google App store for free:
The App helps make you make a complaint in seconds and automatically includes essential detail in the message. Easier verification at the TSP’s end thereby leads to disconnection of the offending telephone number and other penalties depending on the circumstances.
The objective is to develop the App further to achieve the following:
1. Crowdsourcing of information to profile telemarketers.
2. Setting preferences in the DND registry based on subscribers’ classification of messages.
3. Providing spam filtering on the device, with due regard to privacy concerns of the consumer.
4. Providing enhanced services, such as archiving messages on behalf of the consumer or filtering them into folders on the pattern adopted by Google inbox.
The TRAI invites developers to contribute in enhancing the application. The source code for the current version of the App is published on Github at: https://github.com/TRAI-DND/DND.
