Understanding virtual landline numbers

A virtual landline number operates like a standard telephone number, but without the requirement for physical telephone lines. 

With a virtual business phone number, a company can maintain a professional image while harnessing the benefits of cloud telephony.

These virtual local phone numbers are allocated by Ofcom typically through a telecoms provider, and stored in the cloud, enabling businesses to direct them to various locations or devices. This flexibility and mobility allow businesses to manage incoming calls efficiently. 

Their ability to provide businesses with significant cost savings, enhanced flexibility, and a professional, trustworthy local presence. Imagine being a small-scale business in St Andrews, with a local virtual landline number that you can operate from anywhere. In addition it allows small business owners the ability to clearly differentiate their private voice communications from those related to their businesses.

Set up process for a UK virtual landline number

To get a virtual landline number in the UK, a few key steps are required. 

Below we dive into the steps necessary to help you setup a virtual landline including choosing a provider and plan, to selecting geographic and non-geographic numbers for managing calls, integrating a virtual landline within your business communication workflow and more.

1. Choosing a virtual landline provider

In the world of virtual landlines, choosing the right providers includes considering factors such as features, pricing, reliability, customer support, integration, number portability, and scalability.

Support is also important. A small business with up to nine employees, or a micro-entrepreneur, is likely to require a different level of support compared to a multinational corporation.

Therefore, conducting a comprehensive comparison of different providers is key to identifying the one that best caters to your unique needs.

2. Selecting your ideal virtual landline business number (non-geographic or geographic number)

When selecting virtual landline numbers, it’s important to consider whether you need a local virtual landline number or a number with a greater global presence to manage business calls.

The two main types of numbers you can choose from are geographic and non-geographic. Geographic numbers are linked to a specific region or location, allowing you to establish a local presence – in the context of virtual landlines these are often referred to local virtual landline numbers. 

On the other hand, non-geographic numbers can be used globally, offering flexibility and a professional appearance that is not limited to a specific region.

Imagine being a small business based in Welwyn Garden City, but your target market is in Manchester. With a geographic number, you can create a local presence in Manchester without moving an inch from Welwyn! Conversely, if you’re a global business that doesn’t want to be tied down to any specific location, a non-geographic number would be your best bet. 

The choice between geographic and non-geographic numbers truly depends on your business needs and strategy.

3. Understanding plans: pricing, what’s included and choosing a plan

When selecting a plan that caters to your needs and preferences, consider factors like:

  • Your budget
  • Contract term (long term or month-to-month)
  • Number of lines or extensions required
  • Necessary features
  • Call rates & minutes allowances
  • Scalability 

Providers will typically provide a range of plans for prospective customers to cater to the needs of micro-entrepreneurs and small businesses, to global corporations. Considering your core needs in the present, and assessing whether a plan will support future growth and change, is essential to choosing the right plan.

5. Account setup

Setting up an account with a virtual landline provider involves providing personal or business details and setting up a payment method.

The payment options for UK virtual landline services may vary depending on the provider, so it is recommended to visit the websites of virtual landline service providers to ascertain this information. Once you have verified your personal or business information and a payment method, you can proceed to the next step – configuring settings.

6. Configure settings

With a virtual landline, configuration includes setting up call forwarding to your mobile phone or other phones, and configuring voicemail settings, all without the need for a physical telephone line.

To configure call forwarding and other plan-specific features, you will need to access the settings or configuration options for your virtual landline number. A provider may be able to assist you with this setup process, handling part of the process on your behalf or walking you through each step. 

Remember, the steps may differ depending on the virtual landline service provider you select, so it’s always best to refer to their documentation or contact their support for specific instructions.

7. Install necessary desktop or mobile virtual landline apps

8. Integrate your new virtual landline with business software & IP phones

Integrating your new virtual landline with your existing systems and tools can create a seamless unification of communication within your business.

Most providers’ virtual landline support integration with popular CRM systems, email, Google and Apple contact directories, and more. This enables unified management of your communication worfklow and information related to your customers. We encourage you to explore the integrations offered by our UVC softphone extension 

In terms of hardware, a virtual landline can also integrate with IP deskphones if you prefer handling calls with a physical phone that provides a familiar, more traditional call management experience. 

Using a provider’s web-based portal, desktop application or mobile application, you can easily connect to support widely used platforms for managing your business.

Managing calls with your virtual landline

As a user, you have many options for managing calls using your virtual landline service, including a softphone extension accessed on mobile phones and desktops, using traditional deskphones equipped with ATA adapters, VoIP phones, utilising call forwarding to a particular mobile number and more. 

Customizing your communication workflow is another vital aspect. Features such as call forwarding, call whisper, sequential ringing, simultaneous ringing, and time of day routing can be tailored to fit your business needs. Micro-entrepreneurs might prioritize call forwarding to ensure connectivity on the move, while small businesses may leverage sequential ringing for efficient team call distribution. Large corporations could utilize simultaneous ringing and advanced call routing for managing high call volumes, including outbound calls.

We recommend contacting a telecoms specialist to discuss your needs and preferences.

Scaling your business with multiple virtual numbers

Expanding a business often involves scaling up communication strategies, and utilising multiple virtual numbers is a key tactic in this process. With virtual landlines, adding new extensions is easy and usually actioned by the user online via a web management portal. 

The benefits of virtual landlines are wide-ranging, but in terms of scaling up, these include: 

  • Effortlessly addition of new extensions: Quickly add new or remove lines as needed via an online management portal.
  • Direct departmental contact: Assign unique numbers to departments for direct customer access.
  • Enhanced market penetration: Use local numbers in new regions to establish your presence.

When scaling up, you need to be able to expand your business communication system with ease, and have access to features that enhance your communication strategy. Virtual landlines are one of the best options for scalability of voice communications in the modern business environment – and they are equipped with a range of amazing features for entrepreneurs, small businesses and large enterprises.

Transitioning from traditional to virtual landlines with number porting

The transition from a traditional to virtual landline starts is enabled using number porting, which allows you to maintain your existing phone numbers as you move over to a VoIP-based system.  

A telecoms provider will talk you through steps for porting landline numbers to VoIP, and help you set up a virtual landline while retaining your existing number. During the process, a specialist may request documentation for authentication and authorisation, you may need to settle outstanding payments with your current provider, and cancel your landline once the process has been completed.

By 2025 businesses will need to have switched to VoIP in alignment with the discontinuation of the PSTN and WLR3 which will eliminate pure analogue telephony. Virtual landlines offer businesses a future-proof solution for managing their business communications for years to come.

Ensuring compliance and portability

Businesses using virtual landlines should comply with local regulations and understand the number portability options. The regulatory authority for communications in the UK, Ofcom, oversees the regulations for virtual landline numbers. The exact regulations may vary depending on the service provider, so it’s always best to consult with your provider for specific requirements.

As for portability, Ofcom sets out the requirements for porting a number to a virtual landline provider in the UK. Providers must adhere to these rules when customers request to transfer their landline or mobile number(s).
