The proposal to have a single number for various emergency services, approved by the inter-ministerial panel Telecom Commission, would be similar to the '911' all-in-one emergency service in the US.
All existing emergency numbers will be phased out within a year of rolling out 112, depending upon the awareness about this new facility.
"Telecom Commission has accepted Trai's recommendation on single emergency number 112. It will now be drafted by the Department of Telecom and will require Telecom Minister's (Ravi Shankar Prasad) approval. It will be rolled out within months rather than a year," an official source told PTI.
In India, different emergency communication and response systems are in place -- police (100), fire brigade (101), ambulance (102) and Emergency Disaster Management (108).

A person in distress will now need to call 112, which will direct the call to concerned departments immediately for help.
A user will be able to make communication even through SMS and the system will learn about the location of the caller that will be shared with the nearest help centre.
The service will be operated by a call centre like facility, which will have representatives speaking in Hindi, English and the local language.
