Drakos Systems installs and supports VoIP phone systems for businesses across Belfast. We are based in Belfast, we visit your site, we port your 028 number, we configure the system and we train your staff. When something needs fixing, you ring us directly.

VoIP runs over your broadband connection instead of traditional phone lines. It costs less per month, works on desk phones and mobile apps simultaneously, and gives you features that most traditional systems either do not have or charge extra for.

What We Install for Belfast Businesses

028 Number Porting

Your existing Belfast 028 number moves to the VoIP system. Calls continue routing normally during the transfer. No disruption to your customers.

Desk Phones

Yealink SIP handsets supplied, pre-configured and ready to plug in at your Belfast office. Basic models to full touch-screen phones depending on your needs.

Mobile Apps

Staff make and receive calls on their mobile using the office number. Works across Belfast, on the road, or from home. iOS and Android.

Auto-Attendant

Professional call greeting and menu. Route callers to sales, support or accounts without needing a dedicated receptionist.

Call Recording

Record calls automatically or on demand. Useful for compliance, training and resolving disputes. Stored securely and accessible when you need them.

Voicemail to Email

Voicemails delivered to your inbox as audio files. No more missing messages because nobody checked the handset.

Broadband Failover

4G backup routers keep your phones running if broadband drops. Automatic switchover within seconds. Calls divert to mobile as a secondary fallback.

Ongoing Support

Belfast-based support for your VoIP system. Add users, change routing, swap handsets, fix issues. Direct contact, not a call centre.

The ISDN Switch-Off and Belfast Businesses

BT Openreach is switching off PSTN and ISDN phone lines across the UK in January 2027. If your Belfast office currently uses an Avaya, Panasonic or NEC phone system connected to ISDN lines, that system will stop working at the switch-off unless you migrate first.

Two options are available:

We can assess your existing system and tell you which makes sense. See our PBX replacement guide for Northern Ireland for detail on Avaya, Panasonic and NEC migrations.

Why Use a Belfast-Based VoIP Provider

Many VoIP providers serve Belfast remotely, posting out pre-configured phones and providing phone or online support only. That works for some businesses. For others, having someone who can actually visit the site, check the broadband quality, position the phones correctly, test the coverage in each room and train staff in person makes the difference between a system that works and one that causes daily frustration.

Drakos Systems is based in Belfast. We visit before we quote, we install in person, and we are reachable directly when issues come up. No call centre, no support ticket queue, no being passed between teams.

Frequently Asked Questions

Can I keep my 028 Belfast number when switching to VoIP?

Yes. Your existing 028 number ports to the new VoIP platform. The process takes around 5 to 10 working days once the paperwork is in. Calls continue routing normally during the transition so you do not miss anything.

How much does VoIP cost for a Belfast business?

Most hosted VoIP systems cost between £8 and £15 per user per month. Desk phones range from around £80 for a basic handset to £200 for a full-colour touch-screen model. There is no large upfront cost as there would be with a traditional PBX system.

What happens to VoIP calls if broadband goes down?

Calls can divert automatically to mobile numbers if the system detects the office is offline. Staff can also use the mobile app over 4G. We offer 4G backup routers that switch within seconds of a broadband outage, keeping desk phones working as normal.

Do you install VoIP phone systems in Belfast offices?

Yes. Drakos Systems is based in Belfast and installs VoIP phone systems across all Belfast postcodes and greater Belfast. We visit site, port your numbers, configure the system and train staff on the same visit. Same-day site surveys available in most cases.
