Sharma told PTI that in last few days, ever since the issue was flagged by the regulator, there have been "a couple of e-mails" from the company and some "activity".
The regulator -- which has been exchanging e-mails with the global technology giant for over a year to find a solution to the impasse -- is still open to discussions on the Do Not Disturb (DND) app issue which it feels is all about consumer interest and users' right on their own data.
Stating that he was "disappointed" with the outcome so far, especially since the talks with Apple have been going on for nearly a year, the Trai chief said, "Our conclusion is that their approach has not been helpful and that they have been adopting dilatory tactics."
An e-mail sent to Apple on the issue remained unanswered at the time of filing of the story.

The comment comes against the backdrop of the regulator's ongoing tussle with Apple that, according to Trai, is not allowing convergence of the Do-Not-Disturb app onto the iOS platform.
The Trai app allows users to flag pesky calls and unsolicited messages from telemarketers directly to the regulator, and Google's Android operating system supports the app.
The regulator, on Wednesday, kicked off discussions on privacy, security and ownership of data in the telecom sector and market watchers believe that one of the triggers could have been the regulator's displeasure over the ongoing episode and the larger question relating to ownership.
Clarifying that the Trai app does not involve a blanket sharing of call logs or SMSes, Sharma said the app is designed in such a way that users can complain about pesky calls and messages by "consciously sharing details of SMS or calls in case of a complaint".
Rubbishing suggestions that the issue may involve the Trai app not meeting some technology protocols of Apple, Sharma said the talks with the company had not even reached a stage where the latter could comment on the robustness of the app.
