After reviewing comments and inputs from the stakeholders, TRAI has finalised its recommendation on the matter above.
Here are some of the salient features of the recommendation:
1. Migration to a unified numbering scheme which involves large-scale changes in the existing network is not recommended at this stage. However, sufficient numbering resources can be made available.
2. Sparingly used sub-levels may be withdrawn after seeking sub-level whose utilisation from the TSP providing fixed-line services. Those who have not launched their services even after one year of allocation can also be withdrawn after seeking justification.
3. Every SIM-based M2M connections having 10-digit mobile number series should be shifted to the 13-digit numbering series allocated by Telecom department for M2M connection at the earliest.
4. The following scheme can be adapted for enabling sufficient numbering space:
- Dial all fixed to mobile calls with the prefix '0'.
- No change in dialling plan for fixed to fixed, mobile to fixed and mobile to mobile calls.
- Total time of one month to be given to all the TSPs for implementing the scheme.
- All fixed-line subscribes to be provided with the '0' dialling facility.
Last year in May, the Department of Telecom requested to furnish recommendations on the strategies of National Digital Communications Policy 2018 which also included the above factor.
Accordingly, a consultation paper on 'Developing a Unified Numbering plan for fixed-line and mobile services' was issued by TRAI on September 20, 2019, seeking views and comments from stakeholders.
