What is Cloud Telephony: Benefits and How Does it Work?


Table of contents

In the modern business economy, companie­s must employ resourceful strate­gies to communicate effe­ctively both internally and exte­rnally. Cloud telephony has emerge­d as a game-changer in the e­ver-evolving landscape of te­lecommunications, revolutionizing how businesse­s interact with their customers and clients.


A Cloud phone system is ideal for businesses seeking efficient communication solutions while optimizing resources. The expansive cloud infrastructure enables seamless voice and data communication over the Internet. The cloud-based telephony provides capabilities of PBX (Private Branch Exchange) but without the use of traditional copper wires. It leads to improved efficiency, cost savings, and enhanced customer experiences.

What is Cloud Telephony?

Cloud telephony, or IP telephony, is a modern communication technology that utilizes the internet and cloud computing to handle phone calls and other communications. It eliminates the need for expensive hardware investments like traditional on-premises phone systems and offers businesses a flexible, scalable, and cost-effective alternative.


It hosts all the necessary telephony infrastructure and software in the cloud and simplifies business communication. Businesse­s can conveniently access and manage­ their communication services through a use­r-friendly web-based inte­rface or mobile application.

How Does a Cloud Telephony Work?

Cloud telephony leverages Voice over IP (VoIP) technology to transmit voice signals over the Internet. It routes incoming and outgoing calls through cloud servers instead of traditional telephone exchanges, facilitating rapid and reliable communication.


When making a call, the cloud-based VoIP phone system captures voice signals and enables the transmission of these signals over the Internet. The system then converts the voice data into digital packets, which are sent to the VoIP provider’s servers. These servers are geographically distributed to ensure reliable and efficient call routing for callers regardless of their location. After receiving the data, the server processes them while handling various tasks, including call routing, call recording, voicemail, and interactive voice response (IVR).


Organizations typically choose VoIP platforms for cloud phone services. They provide the business with virtual phone numbers, allocate the necessary cloud resources, and manage the infrastructure required for seamless communication. Users can access cloud telephony through web-based interfaces and softphone applications.

Is Cloud Telephony Better than Traditional PBX?

Cloud telephony and traditional PBX both offer effective communication solutions for businesses. However, they differ in infrastructure, flexibility, scalability, and cost-effectiveness.


IP telephony is generally considered better than traditional PBX for several reasons. It eliminates the need for expensive on-premise hardware and maintenance costs, offering cost-effective business communication solutions.

Businesses can quickly scale their telephone needs without substantial upfront investments with a subscription model based on a cost-per-user or cost-per-feature. They can effortlessly add or remove phone lines as per their requirements. This is not the case with traditional PBX systems. It requires physical infrastructure changes, which make scalability time-consuming and expensive.


Moreover, cloud telephony offers flexibility better than the traditional PBX. It allows remote employees and customers to stay connected from anywhere in the world, boosting collaboration and increasing productivity. Traditional PBX systems lack this flexibility, limiting business communications to physical office locations.



Additionally, cloud-based telephony offers much-enhanced reliability and redundancy compared to traditional PBX. Multiple data centers across different locations handle the VoIP phone system to ensure high availability. In contrast, traditional systems are prone to single points of failure, such as power outages or hardware malfunctions.
