Advanced VoIP Systems for Business

Transform your business communications with modern VoIP systems. Cloud-based solutions that deliver advanced features, significant cost savings, and the flexibility to work from anywhere whilst maintaining professional communication standards.

What are VoIP systems and how do they work?

VoIP systems (Voice over Internet Protocol) are business phone systems that route calls over your internet connection instead of traditional phone lines. Synergi Tech designs, installs, and supports VoIP systems for UK businesses, from single-office setups to multi-site deployments with hundreds of users.

A modern VoIP system includes cloud-hosted call management, desk phones or softphone apps, call routing and queuing, voicemail-to-email, video conferencing, and integration with tools like Microsoft Teams and your CRM. Because the system lives in the cloud, adding users, opening new sites, and supporting remote workers takes minutes rather than engineer visits.

With the UK's analogue PSTN and ISDN networks being switched off, every business will need an internet-based phone system. We handle the full migration: assessing your connectivity, porting your existing numbers, configuring the platform, and training your team, with ongoing support included.

Frequently Asked Questions

Get answers to common questions about VoIP phone systems for your business.

VoIP (Voice over Internet Protocol) is a technology that allows you to make phone calls using your internet connection instead of traditional phone lines. VoIP systems convert voice into digital data packets that travel over the internet, enabling features like video calls, voicemail-to-email, and mobile integration that traditional systems cannot offer.

Businesses typically save 40-60% on their communication costs when switching to VoIP. Savings come from lower call charges (especially for international calls), reduced hardware costs, no maintenance fees for on-premise equipment, and the ability to scale without expensive infrastructure changes.

The primary requirement for VoIP is a reliable internet connection. You can use dedicated IP phones, softphone applications on computers or smartphones, or VoIP adapters with existing phones. We provide professional installation and configuration of all equipment as part of our service.
