The quick answer: VoIP (Voice over Internet Protocol) is a cloud based phone system that allows staff to make and receive business calls from any device, anywhere, making it the most practical communications solution for remote and hybrid teams. Unlike traditional landlines, VoIP isn't tied to a physical desk or location. It scales easily, costs less to run, and integrates with tools like Microsoft Teams. With the UK landline switch off arriving in January 2027, businesses still on traditional systems will need to migrate regardless. VoIP is the logical destination.

(Full detail on each of these below — skip to whichever section is relevant to you.)

What is VoIP and how does it work for remote teams?

VoIP (Voice over Internet Protocol) converts voice into digital data and transmits it over the internet, meaning calls can be made and received from any device, anywhere, using the same business number.

Unlike a traditional landline, which is tied to a physical phone plugged into a wall, VoIP is entirely cloud based. A staff member working from home, a client site, or another country can answer calls on their laptop, mobile, or desk phone as if they were sitting in the office.

For businesses managing remote or hybrid teams across the West Midlands and beyond, this flexibility is one of the most significant operational advantages VoIP offers.

How does VoIP support hybrid working?

VoIP supports hybrid working by making a business phone system location independent. Your team's number goes with them, regardless of where they're working that day.

In practice, this means:

• Staff working from home can make and receive calls on their business number without giving out personal mobile numbers
• Teams split across multiple sites can transfer calls, access shared directories, and collaborate as if on one unified system
• Managers can monitor call activity, set routing rules, and manage the whole system from a single online dashboard
• New starters can be set up with a business number in minutes with no engineer visit and no hardware installation required

For businesses with flexible working policies, VoIP removes one of the last remaining reasons to be tied to a physical office.

What is a softphone and do remote workers need one?

A softphone is a virtual phone application installed on a laptop, desktop, or mobile device that allows staff to make and receive calls over the internet without a physical handset.

Most VoIP providers offer a softphone app as part of their service. For remote workers, it is often the most practical option. It turns any device into a full business phone, complete with the same number, features, and call quality as an office desk phone.

For hybrid workers who split their time between office and home, softphones mean there is no loss of functionality on the days they work remotely.

Does VoIP integrate with Microsoft Teams?

Yes! Modern VoIP systems can integrate directly with Microsoft Teams, allowing calls to be made and received within the Teams interface without a separate phone system.

For businesses already using Teams for collaboration, VoIP integration removes the need to switch between applications. Staff can handle calls, messages, and video meetings in one place, with full access to call history, voicemail, and contact directories.

This is increasingly relevant for growing businesses across the West Midlands that want to consolidate their communications onto a single, manageable platform.

Is VoIP call quality good enough for business use?

Modern business grade VoIP call quality is excellent, provided the underlying internet connection is reliable.

Early VoIP systems had a reputation for poor call quality. That reputation is largely outdated. Modern business grade VoIP, running over a stable broadband or leased line connection, consistently delivers clear, reliable call quality comparable to traditional landlines.

The key variable is connectivity. A stable, sufficient internet connection is the foundation a high quality VoIP system depends on. If your current broadband is unreliable, addressing connectivity first is advisable before migrating to VoIP.

Is VoIP secure for remote workers?

VoIP is secure when properly configured and managed, but it does introduce internet based security considerations that traditional landlines do not carry.

Risks include call interception, toll fraud, and denial of service attacks. These are manageable with the right protections in place:

• Strong authentication on all accounts, including MFA where possible
• Regular security reviews of the VoIP environment
• A managed IT provider who monitors and maintains the system

For remote and hybrid teams where staff are connecting from multiple locations and devices, having a managed IT partner who oversees VoIP security is particularly important.

How does the 2027 landline switch off affect remote and hybrid businesses?

Every UK business still on a traditional landline must migrate before January 31st 2027. For businesses with remote or hybrid teams, VoIP is the most logical and practical destination.

BT and Openreach are retiring the UK's copper phone network entirely. Any business still operating on a traditional system after that date will lose phone service. For businesses with hybrid teams already working across multiple locations and devices, the migration to VoIP is a natural fit. It solves the switch off requirement and the remote working challenge in a single transition.

Businesses that plan early have time to choose the right system, port existing numbers without service gaps, and train their teams before the deadline creates pressure.

Frequently Asked Questions

Can remote workers use VoIP on their personal mobile? Yes. Most business VoIP systems offer a mobile app that allows remote staff to make and receive calls on their business number using a personal mobile. The call appears to come from the business number, keeping personal and professional communications entirely separate. Staff do not need to give out personal mobile numbers to clients or colleagues.

What internet speed do you need for VoIP? VoIP calls typically require around 100kbps of bandwidth per simultaneous call, a relatively modest requirement. However, connection stability and low latency matter more than raw speed. A jittery or intermittent connection will affect call quality regardless of advertised download speed. For businesses with multiple staff on calls simultaneously, a leased line or high quality business broadband connection is advisable.

Can VoIP replace Microsoft Teams calling? VoIP and Microsoft Teams can work together rather than as alternatives. Many businesses use Teams for internal collaboration and integrate a VoIP system for external calls, giving staff a single unified communications platform. Some businesses use Teams Phone (Microsoft's own VoIP product) as a standalone solution. The right approach depends on how your team currently uses Teams and what your external calling requirements are.

How long does it take to set up VoIP for a remote team? For most SMEs, a VoIP system can be configured and operational within a few days to a couple of weeks, depending on the complexity of the setup and whether number porting is required. Number porting, (transferring existing business numbers to the new system), takes longer and should be planned carefully to avoid gaps in service. Working with a managed IT provider ensures the migration is handled smoothly from end to end.

What happens to VoIP calls if the internet goes down? Most business VoIP systems include automatic call rerouting. This means that if your main internet connection fails, calls can be automatically diverted to a mobile number, another site, or a backup connection. This built in resilience is one of the advantages VoIP holds over traditional landlines, where a physical line fault can leave a business completely unreachable until an engineer attends.
