The Department of Telecommunications (DoT), in coordination with telecom service providers (TSPs) and law enforcement agencies, has cracked down on 30 telecom setups that were illegally routing international subscriber dialling (ISD) calls over the internet to mobile phone and wireline customers in India in the last four months.
Illegal telecom exchanges primarily use internet connectivity and connect domestic mobile and landline networks for the delivery of calls, which is not allowed as per regulations. Such illegal exchanges pose a security threat and also result in a loss of revenue to the government.
According to an official statement, members of the public are requested to report such illegal establishments to DoT’s call centre. The government has set up call centres having numbers 1800110420 and 1963 for reporting the cases by the public on receiving any international call displaying an Indian mobile/landline number.
