In a move that would streamline the response system and reporting of emergency services, Trai on Tuesday proposed a single nationwide emergency number, 112, that could eventually integrate other existing emergency numbers like 100, 101, 102 and 108 into the proposed helpline number. Trai in its recommendations said people will be able to make calls on 112 from their mobile or landline phones even if their outgoing call facility has been debarred or the service is temporarily suspended. An SMS-based access to the new emergency number, in which telecom operators may be asked to provide location information of the device from where the SMS has been sent, can also be provided, the regulator said. Trai said 112 can be used for all emergency phone calls across the country including for police, fire and ambulance.
