Close to 90% of customer service professionals say today’s consumers have much higher expectations of customer support representatives than in the past.

One of the biggest challenges of the COVID-19 pandemic has been how companies can continue to provide superior customer service in an environment with fewer overall employees, largely remote teams, uncertain delivery dates, and longer support resolution times.

Contact center software is an excellent solution, but with COVID’s accompanying financial crisis, many businesses fear they can’t afford it.

Here, we’ll review the best affordable or free call center software to try out.


Top 7 Free Call Center Software

In determining which providers to include on this list, we evaluated several key factors. To make the cut, the best call center software needed to:

  • Offer one free plan or an extended free trial
  • Have paid upgrade options or advanced add-on features
  • Have native Customer Relationship Management features or be able to integrate with third-party CRM software
  • Have a minimum of two dialing modes (Predictive Dialer, Progressive Dialer, Preview Dialing, etc.)

Some of the call center applications on this list, such as Bitrix24 and GOautodial, have features that are more similar to omnichannel contact centers than strictly call centers, allowing companies to further streamline communication.

Still, because they offer free call center technologies, we’ve included them on this list. Plus, if you can use the same interface for advanced Customer Relationship Management tools, workforce management, and omnichannel communication for free, all the better.

We’ve also included a list of pros and cons for each provider to give you a better insight into the solution’s overall user and customer experience.

The best free call center platforms are:
