"We will take fast decisions. If there is a letter which has come from the Telecom Department or the industry or any agency, we will certainly respond to it," Trai Chairman R S Sharma told reporters on the sidelines of a Nasscom conference here.
Sharma steered clear of specific queries on the latest dispute, in which the cellular operators association COAI has questioned the regulator's discussion paper on inter-connection usage charge.
Reliance Jio has also shot off a letter to Trai, calling for action against dominant players, including Airtel, for denying it inter-connection in "breach" of the licence agreement.
On the issue of inter-connection problems faced by the new operator Reliance Jio, Sharma said, "Whatever the letter, we will reply... Or problems come up, we will respond. If the problem is in our domain, we will sort it out."
"If there is a need to come out with a consultation paper on any issue, I will do that... If there is no need, we will not do that," he replied.
