On-premise Telephony
Secure, reliable telephony solutions built to keep you connected and in control.

On-Premise Telephony for Your Business
On-premise telephony provides a business phone system where the hardware and software are hosted and managed at your own premises rather than in the cloud.
While cloud and hosted telephony are increasingly popular, an on-premise phone system can offer significant advantages for organisations that require greater control, predictable costs, reliable internal communications or support for existing infrastructure.
For businesses with permanent sites, large campuses, legacy cabling or specific requirements around resilience and control, on-premise telephony can be a practical and cost-effective communications solution.
Benefits of On-Premise Telephony
Reliable Internal Calling
On-premise telephony allows internal calls to continue even if your internet connection goes down. This can be particularly valuable for organisations such as schools, universities, hotels and large campuses where reliable internal communication is essential.
Support for Existing Infrastructure
On-premise telephony can be well suited to organisations with established CAT 5 networks or legacy cabling. It may allow businesses to modernise their communications without having to replace all existing infrastructure immediately.
Predictable Long-Term Costs
An on-premise phone system can provide greater predictability over long-term telephony costs, with fewer recurring subscription fees than some hosted solutions. Businesses can also retain greater control over their telephony infrastructure and upgrade it according to their own requirements.
Ideal for Permanent Sites
On-premise phone systems can be particularly effective for organisations operating from one or a small number of permanent locations. They can provide a robust communications platform without necessarily requiring the flexibility of a cloud-first solution designed for highly mobile workforces.
Greater Control and Flexibility
Hosting your telephony system on-site gives your organisation direct control over its phone system hardware, software and configuration. This can be particularly beneficial for businesses with specific technical, operational or integration requirements.
Modern Telephony Features
On-premise does not mean outdated. Modern on-premise platforms continue to support advanced communications features including softphones, contact centre functionality, predictive dialling, call recording, web chat, WhatsApp and SMS integration, and voice AI.
What Do You Need For On-Premise Telephony?
An on-premise telephony solution requires suitable phone system hardware and software to be installed and maintained at your business premises.
Depending on your requirements, this can include an on-site IP-PBX or telephony platform, IP handsets, network infrastructure and softphone applications for mobile devices, laptops and desktops.
The right solution will depend on the size and structure of your organisation, your existing network and cabling, the number of users and sites, and the features you need from your business phone system.

A Device and App for Everyone
On-premise telephony can support a wide range of IP handsets and softphone applications, providing communication options for businesses of different sizes and industries.
High-quality desk phones can be combined with softphones on mobile devices, laptops and desktops, helping employees stay connected whether they are in or out of the office. A range of devices is available to suit different users, roles and working environments.
