The best VoIP phone system is RingCentral, a scalable internet telephony system boasting of a suite of comprehensive features for business calling, messaging, and video conferencing. It streamlines communication, allowing businesses to connect with remote employees, share knowledge with stakeholders, and enhance customer relationships.

The traditional telephone system has been a mainstay in business communication for many years. Since the birth of the internet, however, we’ve seen the advent of new communication systems that have knocked conventional telephony off its perch. Take the voice over internet protocol (VoIP) system, for example.

VoIP brings into the fast-paced business arena the practicality of the traditional telephony system, but with more futureproofing capabilities and benefits.

Your business can reap these benefits (and many more), only if you use the best communication tools.

In this post, we’ll closely examine the top 3 VoIP software, namely RingCentral, Ooma Office, and Lifesize. We’ll look under the hood of these solutions to pinpoint their strengths and unearth their weaknesses (if any). Our scope of comparison will include call management, collaboration, support for virtual meetings, and more. The goal is to lay bare the information you need to pick the best VoIP solution for your business.

In addition to built-in encryption, Lifesize ensures data management and live streaming are secure thanks to permissions, SSO, firewall traversal, and SAML technology. As a result, even when you have a call with your enterprise clients, you can rest assured that no information will be intercepted or leaked.
