Virtual Numbers

Cloud-based phone number services for businesses operating in Africa.

Virtual Numbers

A virtual number, also known as a DID (Direct Inward Dialing) number or cloud phone number, is a phone number not tied to a physical phone line or device. Instead, it's hosted on the cloud and directs calls to a pre-set destination, typically using VoIP (Voice over Internet Protocol). This allows for flexibility and accessibility, as calls can be forwarded to any device or location connected to the internet.

Voice Calling App

An application found in Android and Apple store within a mobile or web application that allows users to make voice calls directly from the app interface. This usually leverages on internet connectivity, offering real-time communication without the need for traditional telephony services.
