The best call centre software and phone systems

The top six call centre telephony systems come from RingCentral, Avaya, 8×8, Nextiva, Cisco, and Freshdesk. 

1. RingCentral

Best for: growing businesses

RingCentral has three call centre packages to choose from. Its basic package is ideal for small scale call centre solutions, with inbound and outbound calling capabilities, interactive voice response (IVR), and automatic call distribution (ACD) three of its main features. 

These features allow call centres to filter out any customers that can be assisted by a recorded message, and free up live agents to handle more complex calls. It also means the call queue is handled in a way that ensures queries go to the agents with the right qualifications.

RingCentral’s most popular offering is its Advanced call centre package. This package allows call centres to interact with customers and clients on an omnichannel basis, including by email, chat, SMS, and social media. 

RingCentral has been developed for use on Android and iOS tablets and phones, Windows-operated computers, and Macs. There are a huge number of integrations available, too, allowing businesses to build a bespoke call centre software package.

Businesses that invest in an Avaya call centre phone system can expect an intuitive user experience – great for onboarding call centre staff – and live monitoring in case a manager needs to assist in a call. There’s also voice-to-text transcription to aid in delivering real-time prompts to call centre staff, and other useful tools to aid productivity.

How to choose the right call centre software for your small business

Look at the call centre software first, and make sure it offers you all the features you need. Will it allow your team to ring out (make outbound calls), as well as take calls? Can you set up things like an auto-attendant and interactive voice response? Can you set up call queuing, and recording?

Make sure the software is scalable. Look at whether you can add sophisticated features like ticket assignment, omni-channel support, and voicemail transcription. Also look at whether it integrates with your existing customer relationship management (CRM) system, or whether it offers a sufficient native CRM system. 

Then look at choosing your call centre phones. Different software packages are compatible with different handsets. This means most suppliers will recommend the right phone package for a complete on-premise or cloud-based call centre phone system solution.

Call centre phone system FAQs

What are some of the burning questions when it comes to choosing a call centre phone system? 

What are the main call centre phone system features?

What are the top six features you should be looking for when it comes to choosing a call centre phone system? 

  • Inbound call management – does it offer interactive voice response and automatic call distribution to make handling calls more efficient?
  • Omni-channel support – to assist customers via multiple digital channels, including email, SMS, and instant messaging
  • Outbound call management – auto-dials numbers to increase the likelihood of getting to a potential customer
  • CRM integration and an open API – to integrate your call center phone system with customer relationship management software and other business tools
  • Call centre reporting – a dashboard that displays things like number of calls taken, cases resolved, and time spent on the phone
  • Interactive voice response – a machine answering system through which callers can complete basic tasks like registration or payment 

What are the benefits of a call centre phone system?

A call centre doesn’t necessarily mean hundreds of employees sat behind a computer screen answering phone calls. It can simply be a couple of employees using a dedicated call management system, which assists with customer enquiries or outbound sales calls. 

Thanks to call centre software and phone system investment, businesses can benefit from:

  • Increased efficiency – calls are directed to call handlers with expertise in a specific area, increasing customer satisfaction
  • Improved customer experience – dedicated and trained call handlers ensure customer calls are dealt with professionally
  • Grow your business – train staff to convert casual enquirers into committed buyers, and show them techniques to retain customers that may have a complaint
  • Manage your sales funnel – dashboards alongside customer accounts will give you a bird's-eye view of your sales funnel 

How much does a call centre phone system cost?

A call centre phone system can cost from around £40 per user, per month for the software alone. 

The overall cost depends on the features you need (for example, whether you’re looking for voice-only or omni-channel customer handling), and whether you’re looking at purchasing handsets, too. 

If you are investing in handsets as well as call centre software, you’ll need to consider the cost of configuring the handsets, plus any installation costs. 

VoIP handsets can cost upwards of £100, while installation costs can range from hundreds to tens of thousands of pounds depending on whether you’re looking at a cloud-based or on-premise solution.
