<span style="color: #222222;">The field units of the Department of Telecommunications, DoT in coordination with Telecom Service Providers and law enforcement agencies have unearthed operations of 30 illegal telecom set-ups in the last four months which were used to route ISD calls. Fraudsters use illegal telecom set-ups to route ISD calls received through internet VoIP illegally to domestic mobile and wireline customers in India. Illegal telecom setups primarily use internet connectivity on one side and connect to domestic mobile and landline network for distribution of call which is not allowed as per regulations. Such illegal setups pose security threat and revenue loss to the Government.<br />''<br />''The Department of Telecommunications has requested the public to report such illegal establishments to its call centre. The call centre having number 1800110420 and 1963 has been set up for reporting the cases by public on receiving any international call displaying Indian mobile or landline number.</span><br />
