The benefits of using a hosted PBX (Virtual PBX / Cloud PBX / IP PBX)

Simple Integration & Maintenance

The third-party provider is responsible for running, managing and upgrading the Hosted PBX. No training or specialty knowledge required for running the phone system or adding extensions etc., as the PBX provider maintains the system.

Managed IT Support Services

A significant reduction in installation, operation and maintenance costs. Low monthly service cost. Potential to reduce telephone costs by up to 80% by leveraging SIP trunks, WebRTC, free calling to remote extensions and reducing the number of telephony lines.

Business Telephony

Superior call quality when paired with the right internet connection. PBX housed in a data centre environment could see an increase in efficiency and stability, as data centres are specifically equipped with cooling and other infrastructure to house them.


Scalable with the growth of your business. Superior integration – including CRM integration. Simple addition of extra lines.

So why partner with eStorm for your hosted PBX solutions?

At the user level, an employee’s IP desk phone connects to a router where the calls, signalling and features all run through an IP-PBX server based at the service provider’s location. This means that the provider is responsible for housing the Internet Protocol Private Branch Exchange (IP-PBX ), as well as maintaining and managing the technology required to provide the services to the phone system.

As a certified 3CX Silver Partner, you can trust eStorm to provide your business with a tailored business phone system.
