SWYX ON-PREM

Swyx On-Prem is designed for organisations that require full control of their communications environment – where systems are hosted, how data is stored, and how the platform is managed.

If your current business phone system is becoming harder to maintain, increasingly fragile, or no longer fit for purpose, it may be time to modernise your on-premise communications. You can do this without moving voice and sensitive data into the cloud.

  • Native Microsoft Teams integration • Works with existing hardware*

WHY CHOOSE SWYX ON-PREM PBX

An on-premise PBX gives you direct ownership of the platform, with infrastructure hosted within your own environment or approved data centres. This approach supports strict security, data sovereignty, and compliance requirements, while allowing you to design resilience and availability to match your operational risk profile.

With a robust, enterprise-grade platform that integrates with modern applications and supports future enhancements, Swyx On-Prem provides a controlled, long-term foundation for voice and unified communications – without compromising governance or architectural preferences.

Want full control of your business telephony?
Swyx On-Premise puts your communications infrastructure in your hands, delivering powerful desk phones, softphones, conferencing and more – all hosted within your own environment.

FULL CONTROL WITHOUT ENTERPRISE-LEVEL COST OR COMPLEXITY

Swyx On-Prem aligns voice and unified communications with your existing IT architecture, security policies, and operational standards – without forcing change where it isn’t wanted.

As part of the Enreach Group, we have the expertise to deliver bespoke solutions you won’t find anywhere else.


BUILT TO FIT YOUR ARCHITECTURE,
NOT REPLACE IT

Swyx On-Prem integrates into established enterprise environments, supporting existing network design, security controls, identity management, and operational processes.

For organisations with in-house expertise, the platform provides flexibility and configurability without prescribing how systems should be designed or operated.

OUR CUSTOMERS
ARE AWESOME TOO

“The team were extremely helpful and knowledgeable, providing strong support across account management, IT, and service departments. I would recommend them as a partner to any business at any stage.”
Jonathan Griffiths
“If we do experience any issues, we get a response very quickly and deal with the same person who sees the fault through to resolution. We have had our account manager for many years who is very accessible and approachable should we have any questions and can get answers to anything we throw her way.”
Andrew Davies
“One company is fully accountable for all of our systems meaning ownership is taken should there be any problems. Having a fully functioning IT system during the last 12 months has been essential and Enconvo have provided this.”
Rebecca Walsh
“Very fast response from Dave Bayley; brilliant customer service. Good to raise a smile whilst rapidly fixing an IT problem. Made my day!”
Juliet Davies
    Glass Manufacturer, Oldbury

    Oh how I wish I had done this sooner! Seamless transition, great communication, from Mike who initially visited and unpicked our telecoms nightmare, through to Lynda, Seth, Scott and Hannah. Everyone was helpful and 100% focused on delivering the promise of a better system and service.

    Manufacturer, Halesowen

    Having worked with Enconvo for over ten years, we find them both reactive to problems and proactive about saving us money. They are a pleasure to deal with, always answer the phone promptly and don’t have the dreaded call centre approach.

    Manufacturer, Shropshire / Global

    We wanted a local telecoms provider that was able to ensure a fast response time in the instance that there were any issues that needed resolving quickly and Enconvo were able to provide us with the communication solution we needed to achieve maximum productivity and efficiency throughout the business.

    Real Estate Agents, Midlands

    We have been a customer of Enconvo for 5 years. Our account managers are fantastic in identifying our needs and ensure that we have the best telephone technology at the best possible rates. Although they are a large company, they have the ‘personal touch’.

    Keith Wiseman

    Employees simply plugged the phones in and followed the over the phone instructions delivered by our engineers. Not only have the video conferencing and plug and play capabilities already made a difference to the way Baumot UK communicates, but the ability to download any apps from the Google Play Store straight onto the phone has been a huge hit

    Phil Lewin

    Another benefit that the school is enjoying is the seamless integration between the phones and its CRM system. This allows the staff to have everything in one place, whether it be contact details of a parent, medical details of a student or voicemails and emails that need responding to.

    Steven Way

    The bespoke Enconvo Contact app works much better than generic, white-labelled apps that we’ve used previously. We really like using the softphones on the laptops

    Peter Phillips

    Easy with great communication…“the telephone system is extremely important for our business
