App to app calling for business


In-App Voice Calls

Globally available VoIP calls from within your apps

What is in-app voice calling or data calling?

App to app voice calling lets you integrate voice calling capabilities inside any app you build. These calls are directly connected to the person at the other end using VoIP. For example, a cab driver will be able to call a rider from within the app, without having to spend money on a voice call.

We used to use a traditional PBX system before. But that doesn’t have the capabilities of Exotel’s IVR system. So, we decided to use Exotel for our IVR cancellation system.
