According to circular,

There will be no change in the dialing plan from fixed to fixed, mobile to fixed, and mobile to mobile calls.

A suitable announcement will be made for the same. This announcement shall be played whenever a subscriber dials a fixed to mobile call without prefixing ‘0’.

 All fixed-line subscribers will be provided with a ‘0’ dialing facility.

A total of approximately 2539 million numbering series is expected to be generated from the above. This will free up sufficient numbering resources for future use.

The new rule follows a Telecom Regulatory Authority of India (TRAI) notification issued in May. Before this rule, the calls made from landlines to mobile phones outside a service area were to be prefixed with ‘0′, and all calls from landline to mobile within a service area could be made without the prefix.
