In this blog let’s understand the working of Voice Calling API and how to gain from its benefits…

Voice API integration is one of the interfaces that 55% of the business are using in 2022 as a ‘critical’ business strategy.  Technically API integration facilitates communications among online applications, builds the brand and reaches clientele across the globe or delivers services remotely.  

According to research analysts, Ipsos, 80% of the surveyed users preferred voice call (using the internet) even though other internet-driving communications like video conferencing, and team messaging are equally effective.  In another 2021 survey  23% of global consumers used third-party mobile apps extensively to place voice calls.

Voice calling API: What is it?

In the case of conventional phone calls, the PSTN providers give a device to the user to make and receive the calls. In the case of voice calling, the API allows any device to be used to connect to the PSTN.   

Voice API is a predefined set of protocols, tools and subroutines, used extensively by developers, to direct the interaction of software components for making and receiving voice calls. The developers connect their internet-based Voice calling application with the Public Switched Telephone Network (PSTN) to allow users to place and receive calls.

Developers can easily benefit from using Voice Calling APIs. First, it takes away the need for a developer to be an expert in telecommunications to build such voice applications. The voice calling API itself executes the entire telephony function and the developer only needs to design and build the customer experience to use it.

Voice Calling APIs also have other advantages – high scalability, high configurability and cost-effective!

Examples of using Voice calling APIs

According to industry reports,[IDC] nearly 30% of the businesses will switch to API-centric integrated communications to drive their digital transformation (DX).

Voice calling APIs are used extensively in Unified Communications as a Service (UCaaS) platform, for cloud-driven automated voice response services, for call tracking, and in applications using artificial intelligence, omnichannel routing and voice notifications. Their simple embedding process for any application needing communication features has led to the enormous use of Voice Calling APIs.

Voice Calling APIs: Benefits

Voice calls API can transform communications approaches in contrast to traditional coding and software development. It will extend the digital product and the services it can deliver reliability in the following ways:

Easy to consume

Since APIs are very easy to use or consume, voice calling APIs are ideal for improving customer experiences. They can lower the operational costs of a business. They are also secure and reliable omnichannel internet-based applications. It helps any business to achieve the end goals with customers or employees.  

Easy to configure

The best advantage of voice call API is their high configure flexibility. It helps businesses not be stuck with a single solution but be centered on customer needs. In fact, the current solution itself can be enhanced by the voice chat API to add messaging functions to legacy software.

Eases call tracking

A major use of the voice call API goes into recording calls automatically. This can also add value by helping with capturing metadata such as the number from which the call was made, and the duration of the call to aid in tracing records of the calls.

Eases customer experience

The most important feature for voice calling API is to have a communication channel to reroute calls to the correct agent based on predefined attributes. Voice calling API ensures an optimized customer experience.

Eases communication scalability 

Voice calling API will allow businesses to reach clientele from any part of the world. Integrated communications will increase and help the business to grow. Voice calling API will not allow making phone calls but purchasing accessories that improve the experience. Along with scalability, substantial savings are also made.

Enhanced Cost-saving

Communications will enhance the purchase of infrastructure, installation premises, hire telecommunications specialists and develop the communication system. The voice calling API will hence save costs. Since API use will cut down on additional employees for maintenance, integration and testing communication capabilities and only need software engineers to build a voice chat app or  integrate an existing application or develop the API simultaneously.

Features of a voice calling API

The features that a voice call API offers varies from one provider to the next. The primary API will support text strings and capture Digital Tone Multi-frequency signaling (DTMF) input from the keyboard. These will help in recording calls, creating outbound calls, and managing conferences. The features that are available on a voice calling API are:


This feature Text-to-Speech (TTS) is integrated with most voice calling APIs to convert text into spoken voice. It is included to improve the accessibility for users

Smart IVR

By using programmable voice calling APIs building multi-level IVR for routing call flows and interaction capacities is enhanced. Simple tasks driven by menu options can be handled autonomously. With the client-first IVR functions:

  • Call routing can be handled intelligently
  • Text-to-speech capabilities are enhanced
  • Calls are recorded
  • Omnichannel experience

Audio conferencing features

Voice calling APIs also include audio-conferencing features. Using this feature to help businesses to connect with their teams and be highly configurable.


Voice call API will improve communications, improve scaling, and configure calls easily at a low-cost business strategy. As an IDC report says, “Digital success includes embracing an API-centric platform and working with a partner that has the right technology expertise to help your organization define, plan, and implement a platform that takes advantage of technology force multipliers..”

As a business, by using voice APIs and SDKs, your digital platforms can programmatically make calls, manage them and receive calls at a very low cost! You can get reliable, fast deploying secure features on any device and unlimited voice calling features when you choose the best voice API provider!
