The Department of Telecom (DoT) grants the approval for TRAI's proposal for landline numbers to add a prefix of the number ‘0’ before making a call, that was put forward in May earlier this year.
The change was made to validate enough numbering resources for both fixed-line and mobile services. Moreover, the Telecom Operators in the country has been instructed to make the necessary arrangements to implement the new system prior to January 1, 2020, by the Telecom Regulatory Authority of India.
As per TRAI, the new dialling pattern can generate around 2,544 million extra number sources for mobile services to fulfil future demands. Beyond this, the change in the dialling pattern will result in creating sufficient numbering space for the telcos.
“The following can be implemented. Calls from fixed to mobile are dialed with the prefix ‘0’. An appropriate announcement can be entered into the landline switches to notify landline subscribers of the requirement to dial the ‘0’ prefix for all landline to mobile calls,” was mentioned in DoT's circular published on November 20. While the TRAI said, "the introduction of a dialling prefix for a particular type of call is not akin to increasing the number of digits in the telephone number."
In May this year, TRAI advised DoT to add an extra digit to a 10-digit into numbering scheme for mobile numbers resulting 11-digit mobile number to increase the total capacity to 10 billion new numbers. TRAI also asked that mobile numbers allocated for dongles should be shifted to 13 digits.
