Has TRAI banned calling facility in tablets in India?

I just got the news that telecom regulatory authority of India - TRAI has banned telephone (calling) facility in tablets sold in India. I searched for more information about this news online but couldn't find any source mentioning it. Is it just a rumor or the news carries some weight?

I don't see any reason why TRAI should be concerned about banning the calling feature of the tablets. If this is true, I wonder what will be the rule for the 'phablets' like Galaxy Note and similar devices.

If anyone knows more about this, please let us know the details.
