Hosted Telephony

What is Hosted Telephony?

Hosted telephony, also known as cloud telephony or hosted VoIP (Voice over Internet Protocol), is a communication service where a third-party provider hosts and manages the business phone system in the cloud. Instead of relying on traditional on-premises Private Branch Exchange (PBX) hardware, businesses connect to their phone system through the internet. Hosted telephony is suitable for businesses of various sizes and industries seeking a modern, flexible, and cost-effective communication solution.

The core benefits of hosted telephony 

Cloud-Based Infrastructure

The entire phone system, including call processing, voicemail, and other features, is hosted on servers in the provider’s data centres, accessed through the internet.


Hosted telephony is highly scalable. Businesses can easily add or remove phone lines and features based on their evolving needs without the need for significant hardware adjustments.

Cost Efficiency

Since there is no need for substantial upfront investments in PBX hardware, businesses can benefit from cost savings. Providers typically offer subscription-based pricing models, making it easier to budget for communication expenses.


Users can access the hosted telephony system from any location with an internet connection, promoting flexibility and remote work capabilities. This is especially valuable for businesses with distributed teams.

Feature-Rich Services

Hosted telephony providers often offer a range of advanced features, such as voicemail, call forwarding, auto-attendants, and integration with other business applications.

Maintenance and Updates

The responsibility for system maintenance, updates, and troubleshooting rests with the hosted telephony provider, reducing the burden on in-house IT teams.

Business Continuity

In the event of a local power outage or other disruptions, hosted telephony services continue to function, ensuring ongoing business communications.
