Find the UCaaS providers and products that meet your needs

The market for UCaaS providers can be confusing, as it consists of hosted versions of on-premises products that have been redesigned for the cloud, as well as virtualized products hosted in third-party data centers.


Unified communications as a service, or UCaaS, has emerged as a way for businesses of all sizes to streamline communications, enhance productivity and manage costs. As a cloud-based alternative to traditional on-premises UC deployments, UCaaS has evolved to provide organizations with several collaboration and telephony features.

Instead of IT departments managing the UC platform on site, a UCaaS infrastructure is outsourced to a service provider's data center, or offered in a public or private cloud environment. Features such as instant messaging, desktop sharing and presence are provided over an IP network. UCaaS generally follows the software-as-a-service model, where businesses only pay for services they use.

Although variations of UCaaS have been in the market for several years, starting with basic voice over IP, organizations are starting to realize the many benefits this technology offers for today's decentralized workforces. UCaaS delivers a consistent user experience that lets users share information across all types of devices and network environments. It also can be integrated with other cloud-based services, including customer relationship management systems and other third-party apps.

This guide will help you determine if your organization could benefit from UCaaS and detail the factors you should consider before making a purchase. We also compare the leading UCaaS providers in the market, examining how they address company size, technical support and their contact-center capabilities. Our individual product overviews provide more in-depth information to help you choose the product that best meets your needs.
