Cost-Effective VoIP Phone Solutions for Hertfordshire Businesses

Digit-IT supplies, installs, and supports modern VoIP phone systems for businesses across Hertfordshire. Cut the cost of your business calls, ditch the old telephone line, and give your team a smarter way to communicate — from the office, from home, or on the go.
Traditional landline phone systems are becoming obsolete. BT’s PSTN switch-off is already underway, meaning that by 2027, all traditional analogue phone lines in the UK will be discontinued. If your Hertfordshire business is still relying on an old landline system, now is the time to make the move to VoIP — and Digit-IT can make that transition completely seamless.
VoIP — Voice over Internet Protocol — uses your existing internet connection to make and receive calls. It’s more flexible, more feature-rich, and significantly cheaper than traditional phone systems. Whether you have two employees or fifty, a VoIP system scales effortlessly with your business and gives your team everything they need to communicate professionally and efficiently.

Unlimited support
How Our VoIP Phone Solutions Process Works?
After a free consultation, we audit your systems and build a support plan around your business. Your systems are monitored 24/7 from day one — issues are resolved before they affect your team. Our Hertfordshire helpdesk is always on hand when you need us.
- Consultation & Requirements Review
A conversation about your current phone setup comes first — how many users you have, how your team works, whether you have remote or hybrid staff, and what features matter most to your business. This shapes everything that follows and ensures the solution fits your actual needs.
- System Design & Recommendation
Based on your requirements, the right VoIP solution is selected and configured for your business. Number porting is arranged, user accounts are set up, call routing is designed, and everything is prepared before a single device goes live — so the switchover is clean and uninterrupted.
- Installation & Go-Live
On the day of switchover, the new system is brought live with zero disruption to your incoming calls. Physical handsets are installed and configured where needed, the softphone apps are set up on your team’s devices, and a full test is carried out across the system before we hand over.
- Training & Ongoing Support
Your team is walked through the new system so everyone knows how to use it from day one. And if questions come up afterwards — or anything needs adjusting as your business changes — our Hertfordshire-based support team is always on hand to help.
Frequently Asked Questions?
What is VoIP and how does it work?
VoIP stands for Voice over Internet Protocol. Instead of using a traditional telephone line, calls are made and received over your internet connection. The call quality is crystal clear, the costs are significantly lower, and the system comes with far more features than a standard landline ever could.
Will VoIP work with our existing internet connection?
In most cases, yes. A standard business broadband connection is sufficient to support a VoIP phone system. During our initial consultation, your internet connection is assessed to make sure it can handle the volume of simultaneous calls your business needs — and if any upgrades are required, you’ll be told upfront.
Can we keep our existing phone number?
Yes. Existing numbers can be ported across to the new VoIP system in most cases. The porting process is handled entirely, so there’s no gap in service and no period where your number is unreachable.
What happens to our calls if the internet goes down?
Call forwarding can be configured to automatically redirect calls to a mobile number if your internet connection drops. This means your clients can always reach you, even in the unlikely event of an outage.
What is the BT PSTN switch-off and does it affect us?
BT is switching off the traditional analogue telephone network — known as the PSTN — by 2027. This means all businesses still using standard phone lines will need to move to a digital alternative like VoIP before that deadline. Getting ahead of this now means you transition on your own terms, with proper planning and no last-minute rush.

Recently I had a pleasure of getting my faulty laptop repaired by Tony Stuart of Digit Computers Ltd. Tony delivers a service that is second to none. Throughout the process of initial telephone consultation, followed by face to face home visit and during the repair process I found Richard to be very professional, reliable and trustworthy. He always gave me good information and sound advise though out the repair process. In the end my faulty laptop delivered to me at home and was not only repaired but also upgraded to a better spec. The laptop is now working as good as new. I have been very happy the work Tony has done to my laptop and would recommend him to anybody who would like any IT work done.
