When Complete Control Matters
Cloud communications have transformed the way many businesses operate — but they're not the right solution for every organisation.
For businesses that need complete control over their communications infrastructure, enhanced security, local system ownership or specialised operational requirements, an on-premise Business Phone System remains an outstanding choice.
At calltime, we believe technology should be chosen to suit your business, not the latest industry trend.

The Best Solution Is the One That Meets Your Objectives
As your Business Communications Partner, we'll help you determine whether an on-premise solution, a cloud platform or a hybrid deployment is the best fit for your organisation.
Built for Businesses That Need More Control
An on-premise Business Phone System places your communications platform within your own environment, giving your organisation greater control over infrastructure, configuration and business continuity — while delivering the advanced functionality expected from a modern communications platform.
Ideal for organisations that…
- Have specific security or compliance requirements
- Prefer to own their communications infrastructure
- Operate across multiple locations
- Require integration with existing business systems
- Need local survivability during internet disruptions
- Want complete control over upgrades and configuration
Enterprise Features Without Enterprise Complexity
Modern on-premise phone systems deliver many of the same advanced capabilities available from cloud platforms — intelligent call routing, auto attendant (IVR), hunt groups, call queues, voicemail to email, call recording, audio conferencing, video calling and mobile/softphone support.

Reliability You Can Depend On
For many organisations, communications are business critical. Local call processing lets many internal telephony functions keep running independently of cloud services — combined with resilient network design and business continuity planning.

Frequently Asked Questions
Quick answers to the questions we hear most. Can't see yours? Book a free review and ask us directly.
What is an on-premise PBX?
An on-premise PBX is a business phone system installed within your own environment, rather than hosted in the cloud. It gives your organisation direct control over the system, its configuration and its data.
Is on-premise better than a cloud phone system?
It depends on your business. On-premise suits organisations that need complete control, local ownership or specialised requirements. We will help you compare on-premise, cloud and hybrid options before you decide.
What is a hybrid phone system?
A hybrid setup combines an on-site system with cloud services, so you keep local control where it matters while adding cloud features such as remote working.
Can an on-premise PBX work with Microsoft Teams?
Yes. On-premise systems can be integrated with Microsoft Teams and other business applications. We will confirm the right integration for your setup.
Who looks after the system once it is installed?
calltime does. We can manage your phone system alongside your business internet, mobiles and Microsoft Teams, so you have one partner for support.
