When it comes to business telephony, Voice over IP (VoIP) has become the go-to solution, providing phone services that run over the internet instead of traditional analog phone lines. The advantages of VoIP are numerous, including improved sound quality, cost savings, and a wide range of additional features. Today, cloud-based VoIP services offer bundled solutions that encompass voice calling, video conferencing, instant messaging, SMS support, and seamless integration with other business software like CRM systems. This integration across multiple channels is often referred to as Unified Communications as a Service (UCaaS).
If you’re considering a new VoIP system for your business, you need to carefully evaluate various factors beyond just cost. Are you looking to provide phone service to remote workers or manage a call center? Do you operate in a highly regulated industry that requires enhanced security measures? To assist you in making an informed decision, we have thoroughly tested and rated leading VoIP solutions, taking into account these critical considerations and more. Here are our top picks:
