Regulations on Providing VoIP Service in India

VoIP Service in India

As we said earlier, using VoIP is legal in India and there are no restrictions on using VoIP services in India. But VoIP service provider should comply with the regulations that (TRAI) Telecom Regulatory Authority of India has clearly mentioned that VoIP and PSTN/PLMN services are allowed to be interconnected in India by telecom companies who hold the following licenses:

1. Basic Service License

2. Unified Access Service License (UASL)

3. Cellular Mobile Telecom Service (CMTS) License

4. Unified License-Virtual Network Operator (UL VNO)

It is legal to provide VoIP services in India if you are an authorized UL VNO (Unified Licensed-Virtual Network Operator) cloud telephony service provider. TeleCMI is one of the authorized VoIP service providers approved by TRAI.

What is a UL VNO License?

UL VNO Licensing is essential to every Cloud telephony provider. TRAI (Telecom Regulatory Authority of India) issues this license under certain requirements. Cloud telephony providers in India must have this license to provide VoIP services in India. A Unified Licensed Virtual Network Operator (UL-VNO) is an internet management service connected with various telecom providers to provide a refined telecommunication solution to customers. TeleCMI is a UL VNO licensed provider under the entity name TeleCMI Technologies.

VoIP Myths That Are Holding You Back in India

Myth 1: The Use of VoIP is in No Way Safe

The VoIP system offers encryption technology, which is more secure than traditional landline systems. Since VoIP uses the data line to transmit voice digitally, it is fast and reliable. Two-factor authentication, advanced monitoring, call encryption, and detailed logs are also offered by some providers like TeleCMI, which can give businesses additional security and give them hope that their private business call data is secure.

Myth 2: Only Large Businesses and Tech Firms Can Use VoIP Effectively.

Compared to traditional phone systems, VoIP offers great features that give small businesses mobility and flexibility. VoIP is more suitable for hybrid working cultures as it allows business employees to work from anywhere, at anytime. This can be a great advantage for small businesses and organizations to stay productive and competitive.

Myth 3: Call Quality on VoIP is Terrible.

The call quality totally depends upon your broadband connection quality. There is a misconception that VoIP requires an ultra-fast internet connection, but this is not true. Your VoIP call quality will be much better than traditional phones with a standard internet connection of 100kbps and decent broadband.

Myth 4: VoIP is Unreliable

If one server fails in a traditional Business phone System, the whole framework goes down, causing customer communication to cease. Cloud-based VoIP phone system uses cloud infrastructure and utilizes multiple servers with 99.99% uptime, so organizations don't have to worry about downtime.

Myth 5: VoIP Services are Expensive

Wrong! It is totally the opposite. VoIP is one of the most cost-effective communication tools compared to traditional phone systems. A VoIP system can save a business's telephone costs by up to 40%. Several businesses spend huge amounts on long-distance communication. These expenses can be significantly reduced with a VoIP connection. Because long-distance calling on a VoIP connection is less expensive than a traditional phone connection.

Myth 6: It's Difficult to Set Up VoIP

If you are planning to implement a communication tool into your business in a short time, VoIP will be the perfect solution. It works like a plug-and-play device, so it can be set up in minutes and does not require any additional hardware to operate. As a result, businesses can reduce their cost of acquisition of physical phones and infrastructure.

Below are a few busted VoIP myths in India that will help businesses understand the use of VoIP.

  • The interconnection between PSTN or PLMN and VoIP is only applicable to holders of a Basic service license, Cellular Mobile Telecom Service (CMTS) license, Unified Access Service License (UASL), and Unified License (access service).
  • Cloud pbx service providers will not need to obtain separate licenses or registrations. Companies in the tele banking, trading, eCommerce, and banking sectors can use the services of an authorized provider.
  • VoIP to VoIP calls are allowed in India, and calls from India to international centers are legal.

Restrictions to Pay Attention

A few regulations are overseen by the TRAI Telecom Regulatory Authority of India and the DoT Department of Telecommunications. There will be no call routing against the interest of the local PSTN service provider for toll bypass.

  • IP to PSTN/landline calls are not allowed, and VoIP calls to PSTN lines within India cannot be terminated. They can never use VoIP gateways within India.
  • The IP phones must work only within their VoIP infrastructure and not connect with WAN or public networks. The calls running through PSTN gateways should not connect directly to VoIP phones or VoIP PSTN gateways in other geographical locations.
