"I have asked my officers to call the operators...understand from them...there may be a communication gap between what regulations say and what the operators understand...there could be some implementation issues, so we will discuss with them and see where the problem lies," Sharma said.
Trai plans to sit with the operators and talk about their difficulties and perceived problem areas, he said but added in the same breath that the issue of pesky calls was a "serious" one, and "must not be undermined".
"The problem has to be tackled and all shareholders must come together to tackle this common problem. We must see to it that compliance burden does not fall unduly on one stakeholder," the Trai chief said.
Voicing concerns over the freshly-minted rules, COAI has maintained that tailoring of systems and use of blockchain technology will involve Rs 2-4 billion cost and 18 months for the rollout, at a crucial time when the sector is financially-stressed.
The implementation timeline indicated by the industry body exceed the stipulated December deadline for operationalising the new system architecture.
COAI has also rued that other markets have not prescribed such stringent requirements and obligations for operators.
The new rules in this regard allow individuals to revoke permission that they have granted to any commercial entity for a service. Subscribers can set preference about days and time bands on which they would like to receive commercial communications as well as indicate preferred modes of communication - call or SMS.
The rules lay down obligations for operators, including evolving code of practices, maintaining records, registering customer choice, and mandate the adoption of blockchain or the distributed ledger technology. Blockchain provides a decentralised database or digital ledger of transactions that everyone on the network can see.
