Best business phone lines – Compared and ranked for 2024

Are you looking for the best business phone lines? In today’s digital era, telecommunication remains a critical element of business operations. UK companies have a plethora of options for their telephony needs, ranging from traditional landlines to modern VoIP (Voice over Internet Protocol) services. Understanding these technologies and comparing options is essential for businesses to make informed decisions that align with their operational requirements and budget constraints.

Read on for everything you need to know when choosing business phone lines.

Understanding the different types of business phone lines


The traditional landline is still prevalent in the UK. It relies on copper wire or fibre-optic networks to transmit voice data. Landlines are known for their reliability and clarity of voice transmission. However, they often lack the advanced features that modern businesses may require.


VoIP technology utilises the internet for voice communication. This versatile solution offers a vast array of features such as call forwarding, voicemail to email, and conference calling. VoIP is highly scalable, making it suitable for businesses of all sizes.


Integrated Services Digital Network (ISDN) allows the transmission of voice and data over digital lines simultaneously. While ISDN offers higher quality voice transmission than traditional landlines, it is being phased out in the UK, with services expected to be completely withdrawn by 2025.


The Public Switched Telephone Network (PSTN) is the aggregate of the world’s circuit-switched telephone networks that are operated by national, regional, or local telephony operators. It’s the traditional setup for most residential and many business customers, providing a dedicated line for telephone communication.

Comparing business phone line providers

When comparing providers, businesses must consider several factors:


For landlines, BT maintains a significant portion of the UK’s network and is known for its reliability. VoIP reliability, however, hinges on internet connectivity. Thus, a provider with a robust infrastructure, such as Virgin Media Business or TalkTalk Business, may be a wise choice.


Providers like RingCentral and 8×8 offer VoIP services with extensive features including video conferencing, analytics, and third-party integrations, which can enhance business communication.


Cost is a significant factor. VoIP solutions are often more cost-effective than traditional landlines due to lower setup and call charges. Companies like Vonage and Gamma offer competitive pricing models for VoIP services.

Customer service

The level of customer service is crucial, especially for businesses that rely on constant communication. Providers such as EE and Vodafone have dedicated business support teams to resolve issues promptly.


As businesses grow, their telephony needs may change. Providers that offer scalable solutions, such as VoIP services from Cisco and Avaya, can adapt to changing business needs without significant new investments in infrastructure.

Transition support

With the ISDN switch-off looming, providers that offer support in transitioning to newer technologies can be particularly valuable. BT, for example, is assisting businesses in migrating from ISDN to VoIP services.

Choosing business phone lines – The verdict

Selecting the right phone line service for a UK company involves balancing various factors including technology type, provider reliability, feature sets, cost, customer service, and scalability. While traditional landlines offer reliability, VoIP and PSTN services provide a blend of innovation, flexibility, and efficiency that can drive a business forward.

As the industry moves towards an all-IP future, it is prudent for businesses to consider transitioning to a VoIP provider, which offers a future-proof telephony solution.

With careful consideration and a strategic approach, UK businesses can choose the telephony service that best suits their needs, ensuring robust and reliable communication that facilitates growth and success.
