VOIP License under DOT

VOIP License or VOIP is Voice over Internet Protocol that uses software and hardware to allow telephonic calls through the internet as a transmission medium in the form of packets using IP instead of PSTN (traditional Circuit transmissions.

With the help of VoIP, the cost of making a call especially the international calls has considerably reduced to nothing. It is also referred to as Internet Telephony, Voice over the Internet (VOI) or IP telephony. CoolTalk, NetMeeting, etc are some applications used for VoIP.

The voice over Internet Protocol inter-connection charges will be set by the Telecom Regulatory Authority of India after amendments are made by the Department of Telecom in a unified license framework. The inter-connection charges have to be paid by a telecom company for allowing its subscriber to make a call which gets added in the final price to be paid by the subscriber to the company.

VOIP License

After a lot of struggle from various telecom companies, on April 1, 2002, the Government of India finally permitted Internet Service Providers (ISPs) to allow internet telephony services to be offered in India. Earlier if the ISP provides internet telephony then their license could be revoked. However, now the gate is open for business. The Department of Telecommunication has granted licenses and approval to many telecommunication companies so that they can start these services. In spite of having poor service in comparison to long-distance services, the consumer will be attracted to it more as they are cost-effective.

The DOT has also revised the ISP License Agreement to include the internet telephony services provision. The Indian Telegraph Act, 1855, the TRAI Act, 1997 and the Indian Wireless Telegraphy Act 1933 was responsible for issuing this authority to the DOT.

The telemarketers and OSP registration are done by TERM (Telecom Enforcement Resource and Monitoring) cells as per the telemarketing/OSP center.

It is the responsibility of the Access Service Providers to ensure that the registration papers of the customers are valid and issued from the DOT’s OSP cell before forwarding it to the telecom resources. If they failed to adhere to the above requirement then action will be taken against them. The application for amendment/ registration should be submitted by the applicants in the Form-1 Performa that is prescribed in the Annexure.
