The CBI, which is racing against time to file a chargesheet in the 2G scam before Mar 31, has already questioned some honchos of telcom firms.
"Some officials of RCOM and Tata among other companies had come for a meeting with the CBI officials. The exercise was undertaken to clear some pending issues," official sources said.
The CBI has to file its chargesheet in the spectrum scam by Mar 31 in the Supreme Court, which has been monitoring the probe by the agency.
It has arrested four people in the case so far -- former Telecom Minister Raja, his personal secretary R K Chandolia, former Telecom Secretary Siddharth Behura and Shahid Balwa, promoter of DB Realty. All four have been sent to judicial custody by a special CBI court.
