Without any ado, let’s get into the details! 

Voice Call API For Enterprise Apps: Why Do You Need It?

Simply put, voice call API is the technology that can integrate VoIP functionality into your app. It enables your users to make and receive calls over the internet, without hanging on the phone lines. 

Guess what? Video call APIs are built on top of a standard and technology called WebRTC, that makes real-time communication seamlessly possible. 

Nevertheless, WebRTC is actively used by giants like Google, Microsoft, and Apple, and is considered the future of building communication into apps and browsers.

Advantages of Voice Call API for Business Apps

An enterprise app that has calling capabilities can yield a rich engagement into your apps and eventually leads to higher conversion rates. But there’s just more!

Let’s look into each one of them one by one. 

1) Automated Voice Response to Customer Queries: In scenarios where your customers need clarification about your products/ services, they expect a quicker turnaround time and instant solution. 

But this is not always possible even if you implement 24/7 support. This is where you’ll need an IVR (Interactive Voice Response). 

So, what is IVR?

Interactive Voice Response (IVR) is an automated phone system technology that allows incoming callers to access pre-recorded information directly, without the need of a human agent. 

Moreover, this IVR system will not only respond to your caller’s inquiries but can also be utilized for a variety of purposes. They include surveys, promotions, polls, payments, brand awareness, and much more.

2) Ensures Relief to the Customers with their Privacy: Assuring privacy over customers’ data is the key behind any successful business. 

With respect to this need for privacy, Voice call API safeguards customers’ privacy and data security using REST API and transaction webhooks.

This way, you can implement reliable and secure omni channel communication capabilities into your apps.

3) High Rate of Productivity: When you integrate calling API into your enterprise app that has a CRM, it typically makes project management easier and smoother. 

On the other hand, if you’d like to set up a helpdesk, it is easy to connect your support representatives and your customers. On the whole, you can leverage a productive work ecosystem with communication capabilities.

4) Loop Call Flows, have control over calls: Gone are the days when employees in an organization need to connect to different departments or have to set call backs. 

With a call transfer and call forwarding functionality, you can easily get things done within minutes, and increase business conversions.

5) Enhance Tracking: Sometimes, users prefer to record their calls for future purposes. With an API, you can let your users record, track and retrieve calls automatically.

Looking to Build a Customizable Voice Chat Solution?

Why Choose a Programmable Voice API for a Successful Business?

A programmable voice calling API comprises basic to advanced features for rapid and smooth communication. They may include outbound calls, call recording and conference call management. 

Here is a list of in-app communication features that you may need to include, for the success of your business app. 

1) Media Streaming

Let’s say that when a call is initiated, the API duplicates, delivers, analyzes and returns them in real-time. Fortunately, the API will not allow the second recipient to occupy the call stream. 

So worry not! Your users will not degrade the quality of the calls or face drop face connections. 

2) Audio Conferencing Globally

By using APIs, you can implement  audio conferencing capabilities into your enterprise apps. This enables the application to connect people and teams across the world with highly configurable behavior.

3) Browser Complexity

Every web browser, Android, and iOS are different as they implement voice calls differently. The quality of API can have a great impact over the platforms as the low-level API puts the cross-platform to work. But the high-featured APIs can take care of all browsers and platform differences automatically.

4) Handling Browser and Platform Updates

An API lets your web browsers and mobile devices get updated automatically. This enables the user to have new functionality every time they use the platform.

5) UI and layout design

Voice call APIs offer a UI kit and the full-featured API gives a drop-in video widget. You can customize the features using CSS and JavaScript for layout.
