Ready to build better conversations?

Simple to set up. Easy to use. Powerful integrations.

Get started

While omnichannel contact strategies have become the new standard for businesses, at least 71% of customers across age groups still call companies for live phone support.* With that in mind, you need a strong call center phone system to offer seamless voice communication to your customers. 

These platforms play a strategic role in improving your customer-facing services and sales performance, which is why it’s so important to choose the right one for your business. 

In this buyer’s guide, you’ll find a comprehensive comparison of 10 top call center software systems. We review key features, integrations, pricing, and pros and cons to help you make the best decision for your business. 

TL;DR - Key takeaways

Key types of call center phone systems

To choose the right call center software, you need to first decide which type of system is the best fit for your business, whether that’s on-premise or cloud-based. Here’s a brief look at each option.

On-premise systems

On-premise business phone systems require you to set up infrastructure and hardware at your office. These solutions can work for enterprises with in-house IT teams that have the capacity to conduct regular system maintenance. 

This method offers businesses high call security, quality, and reliability, but it requires a big upfront hardware investment. Plus, scalability is complex and expensive, because it requires you to physically add more lines to your plan, and you’re limited in terms of hybrid and remote work setups. 

Cloud-based systems

Cloud-based solutions leverage VoIP technology to transmit calls over the internet, and are hosted by a third-party phone provider, like the tools on this list. Cloud business phone systems are more cost-effective than on-premise setups, as they don’t require an initial hardware investment or ongoing maintenance. 

Additionally, they’re very flexible, as you only pay for seats and features you need, and enable access from any location with internet access. 

Aircall is the perfect example of a highly customizable and scalable cloud call center software solution. It’s incredibly easy to set up, doesn’t come with high installation costs, allows your team to work from anywhere with an internet connection, and enables you to add new lines in over 100 countries and tack on features as your business and team grows.

Must-have features in a modern call center phone system

The right call center software for you should include, at a minimum, the following features. Beyond these, it’s important to consider your unique business needs to decide which additional functionalities are essential for your team.

Interactive voice response (IVR) with smart call routing capabilities leads to: 

• Improved customer satisfaction by reducing wait times

• Lower abandoned call rates through efficient call handling

• Reduced waiting queues thanks to proper call redirection 

• Increased self-resolution, as customers can often find the information they need without assistance

• Guarantee high-quality service by guiding agents in real-time

• Support new agents during challenging interactions by providing suggestions during live calls

• Improve service by monitoring key call metrics to assess performance and identify areas for improvement

Call center analytics

You should be able to gain access to historical and real-time call center analytics and insights to:
