On-Premise PBX

Fully managed on-premise PBX systems delivering powerful business phone functionality in the most cost-effective and flexible way.

Remove your communication challenges

On-Premise PBX offers all the same benefits as a hosted PBX solution (including management of your system), with the only real difference being that your telephone switching system (either virtual or physical) resides at your location instead of at the providers location.

An On-Premise PBX system is not locked into solely providing telephony for the location it resides in. Your on-premise PBX system may be used to control phones or link to other PABXs at other sites and even allow Internet based phones to act as extensions of the phone system.

The benefits of on-premise PBX systems

Budget Friendly

Monthly fees can be cheaper due to using your own infrastructure.

Made for complex workplaces

On-Premise PBX makes more sense in terms of efficiencies for larger and more complex use cases and environments.

Conlocation & Server Hosting
Connecting Equipment

Having an on-premise PBX system allows for the connection of other equipment at that location that may not be able to be delivered via a data center.

Private Cloud 1
Securely Hosted

Our Hosted PBX solution is hosted securely in our cloud and removes the need for you to manage and operate your own PBX hardware and systems on your premise.

eStorm's simple and managed local PBX solution tailored to your needs

A hosted PBX is not always the best solution for your phone system. If you are running legacy equipment, or perhaps aren’t confident in your internet connection, an on-premise PBX system may be a more suitable option.

With an on-premise PBX, or local PBX, you still can benefit from many of the features of a cloud PBX. eStorm can set up a solution that provides you with redundancy and an uptime guarantee to ensure continuity and business confidence.

Our on-premise PBX solutions enable you to determine the level of control you want over your systems. Create users, voice recordings, and call flows yourself, or leave it up to our team of professionals to do the work for you.

The internal IT Manager at Silky Oaks left with no notice and very little documentation. Silky Oaks approached eStorm to assist in keeping their systems operational while they assessed their ongoing IT requirements.


Lighthouse Christian School promoted their junior technician to a management role after the departure of their previous IT manager. The new manager felt he was still developing his IT knowledge and experience, and thus would not be able to single-handedly run the school’s IT. LCS then endeavoured to find a Managed Service Provider that could provide supplemental IT support and services.


To meet the needs of a large client, Liquid Animation worked with eStorm to architect a solution that allowed international animators to seamlessly access data. This was achieved using a combination of cloud-based work stations and Amazon Web Services.
