Call us on 028 9693 6777.

Choosing a VoIP Provider in Belfast

A cloud phone system, or VoIP, runs your calls over your broadband instead of through a box in the comms cupboard. Calls ring on a desk phone, laptop or mobile, and the same app handles team chat and video meetings.

You may also hear it called a hosted PBX, and the nibusinessinfo.co.uk guide to business phone systems is a good impartial starting point.

When a customer rings your 028 number, whoever picks up can message a colleague, transfer the call to the Dublin team or start a short meeting without leaving the app. AI summaries note the outcome for everyone.

As a VoIP provider for Belfast firms, we set up and test your system before it arrives, move your 028 numbers across and look after you from one UK support team once you are live.

Supporting Businesses Across Belfast

We work with everyone from a two-person practice near Donegall Square to firms with several sites across the region. Each business phone system in Belfast we set up is built around your team, not squeezed into a fixed bundle.

We start with who answers first, where your staff spend the day and which tools your staff use alongside the phones. Choosing between phone systems in Belfast can feel like a maze of jargon, which is why we explain the options in plain English.

With a business phone system in Belfast, offices in the city, Lisburn, Newtownabbey, Holywood, Carrickfergus and Bangor can share one directory. A call to the city centre can be picked up in Lisburn or passed straight to a colleague in Bangor.

Keep Your Belfast 028 Number When Moving to VoIP

Moving to a cloud phone system doesn’t mean changing the number your customers know. Where porting is available, your Belfast 028 number moves to your new business phone system in Belfast.

You can then answer calls on desk phones, computers and mobiles, and customers still see the same Belfast number they have always called.

✓ Keep your existing 028 number where porting is available
✓ Route calls between Belfast teams and locations
✓ Answer business calls from desktop or mobile apps
✓ Plan number transfers before your agreed changeover date

VoIP, UCaaS and CCaaS Explained

VoIP, which stands for Voice over Internet Protocol, sends your calls over the internet instead of a copper line.

Your staff and callers notice no difference on the line. That is one reason so many local firms have moved to VoIP phone systems in Belfast. Our guide to what VoIP means has more detail.

UCaaS means Unified Communications as a Service. It puts calls, video meetings, chat and your team directory in one app. Staff log in once, with no juggling between tools. Our UCaaS page explains each part.

CCaaS means Contact Centre as a Service. It is built for teams whose main job is talking to customers.

It adds call queues, routing to the right person, live screens showing who is waiting, and call scoring. See our UCaaS and CCaaS solutions page for the full range.

A business phone system in Belfast does not have to start big. Most offices start with UCaaS for everyday calls, meetings and chat.

As enquiries increase, contact centre features like queues and reporting can be switched on. Everything runs on the one platform, with nothing to rip out.

Unsure where to start? Our Belfast team can compare the options with you.

Key Features of Your Business Phone System

No two teams use their business phone system in Belfast the same way. We choose features to match how you really work. Options also include voicemail to email, business text messaging and presence, which shows you who is free.

  • Auto Attendant

    A friendly recorded greeting sends callers to sales, accounts or support. Nobody in your Belfast office has to answer all the calls.

  • Call Queues

    When lines are busy, callers wait in a queue and are answered in order. You set the rules to suit how your team works each day.

  • Call Routing

    Callers reach the right person, team or site based on the time of day and who is free.

  • Mobile and Desktop Calling

    The app puts your business number on any laptop or mobile, which means fewer missed enquiries. Business mobiles work alongside desk phones.

  • Call Recording

    Recordings help with coaching and compliance. They are kept in warm storage for 30 days, extendable to 180 days, with cold storage for up to 10 years.

  • CRM Integration

    Depending on the CRM you use, a customer’s record can appear as their call arrives. Staff spend less time hunting for details.

  • Microsoft Teams Integration

    Already using Microsoft Teams? Direct routing brings Teams Calling onto your 028 number, and colleagues make and take calls without leaving the app.

  • Support From People Who Know Your Setup

    Call our UK-based team on 028 9693 6777. They keep an eye on the platform, deal with your questions and make changes when you ask.

  • Security and Compliance

    Our platform runs on infrastructure certified to ISO 27001, SOC 2 Type II and Cyber Essentials Plus. Read the NCSC overview or IASME’s certification guide to learn more.

Contact Centre Tools for Busy Teams

Belfast has plenty of customer service and support teams, from city centre offices to business parks near the airport. Your business phone system in Belfast can grow into a full contact centre with the tools below, including a live wallboard.

That screen shows supervisors how many callers are waiting, the longest wait, the service level and which agents are free. Explore our contact centre solutions for the full range.

Talk to us about your contact centre
  • All Channels in One Queue

    Customers can reach you by phone, email, chat or social media. Each message joins the same list for your agents to work through.

  • Routing by Skill

    Each caller is matched with the agent who knows their subject, not simply the next person free.

  • Live Dashboards

    Team leaders see queue length, who is free and how long people have waited. They can listen in or join a call when needed.

  • Coaching, Rostering and Call Scoring

    Forecasts based on past call volumes help you staff each shift. Call scores point coaching at real examples.

  • Outbound Messaging

    Send appointment reminders and service updates in bulk while agents stay focused on incoming calls.

  • Live Guidance for Agents

    Prompts appear on screen during a call, helping newer staff find the right answer quickly.

  • Recordings You Can Find

    Recordings stay searchable. When a call is disputed, you can find it and play it back quickly.

  • An AI Receptionist and Summaries

    A virtual agent can answer common questions and route callers. AI-generated call summaries save your team typing up notes.

Built for the Way Belfast Does Business

Services drive the Belfast economy. Law and accountancy firms cluster around Chichester Street and the courts. A cyber security sector has also grown out of university research at Catalyst in the Titanic Quarter.

Away from the offices, Belfast Harbour, the city’s two airports and the estates at Duncrue and Mallusk keep manufacturing, engineering and logistics moving. Each sector handles calls differently, and we plan each system around the work rather than one fixed package.

Tell us about your sector and we’ll suggest a business phone system in Belfast to suit it.

One Business Phone System in Belfast for Both Sides of the Border

Plenty of Belfast firms sell to customers in Dublin, Dundalk and Drogheda as well as Newry and Lisburn. InterTradeIreland offers practical support for trading across the border.

We supply business phone systems in the Republic of Ireland too. A single business phone system in Belfast can serve customers and colleagues on both sides of the border.

  • An Irish Number Alongside Your 028 Number

    Add a Republic of Ireland number for any area, from Dublin 01 to Cork 021. Southern customers ring a local number that reaches the same team.

  • One Team, Wherever They Sit

    Staff in Belfast and the Republic share one directory, one set of call queues and one call history. Passing a call to Dublin is simple.

  • Separate Hours and Bank Holidays

    Northern Ireland and the Republic keep different bank holidays, from the Twelfth to St Brigid’s Day. Each number can follow its own calendar and greetings.

  • One Supplier North and South

    Instead of a separate provider on each side of the border, you deal with one UK-based team. We set up, support and change your whole system.

From the Republic, callers dial 048 and the eight-digit local number. Our Belfast line then becomes 048 9693 6777. Ask about adding an Irish number when you request your quote.

Why More Firms Are Moving Calls to the Cloud

More Belfast firms are moving their telephone systems to the cloud, and it helps in three practical ways.

Hybrid working. Your number, directory and call history follow each person to the office, home or a site visit in County Down, on a desk phone, mobile or the app.

Business continuity. If a power cut or broken line hits the office, staff carry on from anywhere and calls can divert to mobiles or a backup number. That is a simple disaster recovery plan with no second system to run.

Voicemail to email. A missed call leaves a message in your inbox that you can play on a laptop or phone between meetings.

Your 028 Number Goes Wherever Your Team Goes

From an office near Donegall Square to a site visit in Lisburn or a home office in Holywood, your team can answer the same 028 number on the app, a laptop or a desk phone.

Customers always see your Belfast business number, never a personal mobile, and nobody needs a second phone in their pocket.

Preparing Your Belfast Business for the PSTN Switch Off

Openreach plans to retire the PSTN, the UK’s old landline network, on 31 January 2027. If your Belfast business still uses analogue or ISDN lines, check your numbers, call flows and connection before then, not just your handsets.

A cloud business phone system replaces those lines. Calls travel over your internet connection, with call routing, mobile working, voicemail, call recording and business continuity options.

Blake Telecom can review your current phones, check your connection and plan the move around your users and call flows. Eligible Belfast 028 numbers normally move across with you.

The challenge

When new owners took over The Inn Castledawson in County Londonderry, the hotel’s phone system was outdated and hard to manage. Guests, suppliers and staff all depended on it, and it was holding the business back.

What we installed

We replaced the old system with a cloud phone system and 16 handsets for the hotel team. Everything was set up and tested before it arrived, and the new system went live in 2021.

The result

Staff now have a simple, flexible phone system that can change with the hotel. Our technical team has stayed involved since go live, helping the hotel adapt how it handles calls as the business has grown.
