"We have written to all the private operators to get information about the employees who left MTNL or BSNL and have joined private companies... we want to know that they took permission from us," Communications and IT Minister Dayanidhi Maran told reporters at the Economic Editors' Conference in New Delhi.
Asked if there was any possibility of link between the employees and ex-employees of two PSUs and private operators with the alleged routing of international calls as local ones, Maran said "there is no such complaint with us."
Maran emphasised that DoT has taken up the issue of grey market in telecom very seriously and all efforts were being made to check it.
"Soon we will come out with advertisements asking for public support for checking the illegal routing of calls and set up a toll-free number to receive complaints," he said.
Maran appealed to call the toll free number immediately if a subscriber gets an international call with inaccurate Caller Line Identification.
On the issue of high Access Deficit Charge being levied on private players as the root cause of grey market, Maran said the concept of ADC was prevalent world wide and even here it was being reviewed regularly.
Maran, however declined to comment on whether the ADC portion needs to be reduced immediately to curb the grey traffic especially in the incoming international call segment.
