A Centralita virtual en la nube (Cloud‑Based Private Branch Exchange) is a virtual phone system that delivers enterprise‑grade calling features over the internet instead of traditional on‑premise hardware. For businesses seeking flexibility, scalability, and cost efficiency, Cloud PBX has become the new standard for professional communication.
What Is Cloud PBX?
A Centralita virtual en la nube is a hosted telephony system where all call routing, switching, and management functions run on remote servers maintained by a VoIP provider.

Cómo funciona la centralita virtual en la nube
Cloud PBX uses VoIP (Voice over Internet Protocol) to transmit voice data over the internet.
When a user makes a call:

- The recipient hears the audio in real time
This process is fast, secure, and optimized for high‑quality communication.
