VoIP Phone Systems for Manchester Businesses: The Complete 2026 Guide

If your business is still running on a traditional landline phone system, you’re paying too much and getting too little. VoIP phone systems for Manchester businesses have transformed the way companies communicate — and if you haven’t made the switch yet, 2026 is the year to do it.

At Coretek Solutions, we set up and manage VoIP systems for businesses across Manchester and the North West. This guide covers everything you need to know — from what VoIP actually is, to how much you can save, and what to look for when choosing a provider.

What Is VoIP and How Does It Work?

VoIP stands for Voice over Internet Protocol. Instead of sending your voice down a copper phone line, VoIP converts your call into data packets and transmits them over your internet connection — the same way emails or video calls work.

For your team, it feels exactly like a normal phone call. They pick up a handset (or use a softphone app on their laptop or mobile), dial a number, and talk. Behind the scenes, everything happens over your broadband connection rather than BT’s ageing copper infrastructure.

This matters a lot for Manchester businesses because the UK’s PSTN (Public Switched Telephone Network) — the traditional landline network — is being switched off in December 2025. BT Openreach has already begun the rollout. If you haven’t moved to VoIP yet, you’ll be forced to eventually. Better to do it on your terms, with time to plan.

Why Manchester Businesses Are Switching to VoIP

The PSTN switch-off is one driver, but it’s not the only reason companies are making the move. Here’s what’s actually compelling businesses across Manchester, Sale, Altrincham and the wider North West:

1. Significant Cost Savings

Traditional phone systems come with line rental fees, per-minute call charges, and expensive hardware maintenance contracts. VoIP eliminates most of these costs. Most plans offer unlimited UK calls as standard, and international call rates are a fraction of what BT charges. Businesses typically save between 40% and 70% on their monthly phone bills after switching.

2. Work From Anywhere

Your office phone number follows you wherever you go. Whether your team is in the Manchester office, working from home in Didsbury, or on a client visit in Leeds, they can make and receive calls on their business number. With a softphone app installed on their laptop or smartphone, your staff are always reachable — without giving out personal numbers.

This has been a game-changer for businesses that adopted hybrid working after the pandemic. VoIP makes the phone system location-agnostic.

3. Easy to Scale

Adding a new extension on a traditional PBX system often meant a visit from an engineer and a significant bill. With VoIP, adding a new user takes minutes in the admin portal. You’re not tied to physical lines — you simply provision a new account. This is particularly useful for growing Manchester businesses that are adding headcount quickly.

4. Professional Features Included as Standard

VoIP systems come loaded with features that traditional phone systems either can’t do or charge a premium for:

• Hunt groups — route calls to the first available team member automatically
• Auto attendant / IVR — “Press 1 for sales, press 2 for support…”
• Voicemail to email — receive voicemails as audio attachments in your inbox
• Call recording — essential for compliance in many industries
• Call analytics — see call volumes, wait times, and team performance
• Video calling — built into many VoIP platforms
• CRM integration — calls can log automatically against customer records

These features are typically included in your monthly subscription — not bolted on as expensive extras.

5. Disaster Recovery Built In

What happens if your Manchester office floods, loses power, or becomes inaccessible? With a traditional phone system, your phones go dead. With VoIP, your team can instantly switch to mobile apps or home setups and continue taking calls as normal. For business continuity, it’s a massive advantage.

What About Call Quality?

The most common concern we hear from Manchester businesses is call quality — will it sound as good as a landline? The honest answer: it depends on your internet connection, but with a decent broadband or fibre line, VoIP call quality is excellent. Many users say it’s better than their old landline.

The key is ensuring your network is properly configured. At Coretek, we always assess your connectivity before recommending a VoIP solution, and we configure Quality of Service (QoS) settings on your router and switches to prioritise voice traffic. This prevents call quality being affected by someone running a large download at the same time.

For businesses in Sale, Manchester and surrounding areas with older copper broadband, we may also recommend upgrading to a faster connection as part of the project — which usually pays for itself in saved phone costs anyway.

Choosing a VoIP Provider: What to Look For

Not all VoIP providers are equal. Here’s what to check before signing a contract:

• UK-based support — phone problems are urgent; you need someone you can actually reach
• SLA guarantees — what’s the uptime commitment and response time?
• Number porting — can they keep your existing business number?
• Contract length — avoid being locked into long terms with a new provider
• Headset and hardware compatibility — will your existing equipment work, or do you need new handsets?
• Microsoft Teams integration — if your team uses Teams, a provider that integrates with Teams Calling is worth considering

Coretek works with several proven VoIP providers and will recommend the right one based on your team size, budget, and technical setup — not based on which one pays us the highest commission.

VoIP and Microsoft 365: Better Together

If your business is already using Microsoft 365 (and if you’re not, read our Microsoft 365 guide for Manchester businesses), you have another option: Microsoft Teams Phone.

Teams Phone adds a calling plan to your existing Teams subscription, turning Teams into a full business phone system. Your team can make and receive calls to external numbers directly from their Teams app — no separate softphone needed. It’s particularly compelling for businesses that are already deep in the Microsoft 365 ecosystem.

How Much Does VoIP Cost for a Manchester Business?

Pricing varies based on the number of users and features required, but as a rough guide for small to mid-sized Manchester businesses:

• Basic VoIP plans: £5–£10 per user per month
• Mid-tier with call recording and analytics: £12–£20 per user per month
• Microsoft Teams Phone: from around £8 per user per month (on top of M365 subscription)
• IP handsets: £40–£120 per desk if you need physical phones

Compare that to a traditional PBX system with line rental, per-call charges, and hardware maintenance — most businesses see the return on investment within the first six to twelve months.

The PSTN Switch-Off: Don’t Leave It Too Late

BT Openreach’s PSTN switch-off is already underway in parts of the UK, with the full national shutdown due to complete by the end of 2027. That means traditional landlines and ISDN connections will stop working entirely.

If your business is still on PSTN or ISDN, the clock is ticking. Moving to VoIP while you have time to plan — rather than scrambling when your lines stop working — is the sensible approach. We’re already helping businesses across Greater Manchester make this transition smoothly, with minimal disruption to day-to-day operations.
