Builder Studio lets you build feature-packed VoIP apps for different VoIP services, including device-based VoIP services, software-based VoIP services, mobile VoIP Services and finally, web-based VoIP services. Let’s dig into these a little bit:

Desktop apps: These VoIP apps are popular among businesses organisations (especially if they use BPO/KOP/LPO – where services are outsourced and communications between organisations often oversees are essential for day-to-day running of the business). These VoIP apps include facilities like voicemail, call recording, ring-all, call forwarding, call analytics and many more custom features. We can help you create anything you can dream up and build your VoIP calling apps for Windows and macOS.

Web apps: These cloud-based web apps work similarly to desktop apps and can be accessed through any web browsers. Simply by logging into a cloud-based web application, you can use VoIP services from any devices (all you need is a web browser and an internet connection). It’s simple to start building your VoIP web apps today.

Mobile apps: There are hundreds of VoIP apps that provide messaging and Voice over IP services. Some of the most famous VoIP apps are Viber, WhatsApp, WeChat and Skype. The market is huge and growing, so, what are you waiting for? Build your VoIP mobile apps for iOS and Android without coding a single line, with us.

What features should your VoIP application have?

VoIP applications vary depending on the type of services they’re built for. Features of a desktop application (developed for corporate users) and mobile applications (developed for the end-users) may differ as they are being used for different purposes. We suggest you spend quality time researching the kind of app you’re planning to build and features your users will be looking for. And maybe throw in a few innovative ones they won’t expect.

Must-have VoIP application features:

Calls: Allows your users to call any contact from their contact list. Calling may be free or you can add a cost. Viber, one of the most popular VoIP apps, helps users to call any number anywhere – it’s free for Viber users and paid for non-Viber users.

Video calls: Video calling is considered to be a must-have for mobile users. VoIP calling apps like WhatsApp and Viber allow their users to make video calls – and support them cross-platforms.  

Group calls: this feature allows hosts to add multiple people to their call. The host can add or remove any contact during the call. 

Voicemails: What if someone misses the call? Voicemail is the answer. This feature lets users leave a voicemail to the dialed number if that person doesn’t pick up.

Blocking a call: What about spammers? This feature solves the problem. It’s a one-tap solution to spammers where users can block a contact by tapping the block feature in their app.

Call recording: It’s not important but could be a nice additional feature if you allow your users to record a call. Highly recommended for VoIP applications built for business organisations.

Realtime messaging: Realtime chat or messaging is one of the most important features of your VoIP application. It allows your callers to send and receive messages over internet protocols in realtime. 

Notes: It doesn’t affect the functionality of your application but could be an addon to your platform. This feature works like a notepad and could be used to keep track of daily to-dos.

Contacts: Let users add and manage their contacts easily with this feature. This list syncs with the contact list on your phone. 

In-app purchase: How will you make money? This app feature is utterly essential if you have a monetisation model like pay per month or pay per minute subscription plan. 

Invite friends: Let your users recommend your app to others. This feature allows them to share app links to their social handles and other messaging apps.
