Unified Communications as a Service (UCaaS) Providers

What is Unified Communications as a Service (UCaaS)?

Unified Communications as a Service (UCaaS) centralizes and delivers business Unified Communication (UC) tools such as voice, video, chat, and collaboration in one cloud-based platform. With UCaaS, teams can seamlessly and efficiently manage all their communication channels in one place and easily toggle between phone calls, instant messages, and video meetings throughout the day without having to access and manage multiple systems or tools. UCaaS is a cloud-based system, so employees can access communication tools and features on any device with an internet connection to stay seamlessly connected while traveling or working remotely.

UCaaS is popular among companies of all types and sizes, due to benefits such as:

  • Improved internal and external business communications, enabling remote and hybrid work,
  • Reduced operating costs,
  • Increased team productivity and efficiency,
  • Enhanced employee collaboration and content sharing,
  • Increased control of business communication workflows.

UCaaS systems are hosted, managed, and maintained by the provider, so companies do not need to invest in any costly hardware or build and maintain the IT infrastructure needed to support unified communications. UCaaS vendors also manage system updates, upgrades, and security, so companies always have the most updated, secure, cloud-based communication tools available in one interface.

While UCaaS software offers substantial communication functionality on its own, it can also be integrated with other business systems, such as contact center software and Customer Experience (CX) tools, to further streamline an organization's internal communications and customer-facing workflows.

What is the difference between UCaaS and CCaaS?

Unified Communications as a Service (UCaaS) provides cloud-based, centralized communication tools such as voice, video, and chat to streamline and improve internal business communications.

What is the difference between UCaaS and CPaaS?

Unified Communications as a Service (UCaaS) systems provide a unified suite of prebuilt, cloud-based tools to facilitate business communications via voice, video, and chat, while Communication Platforms as a Service (CPaaS) offer APIs that businesses can use to integrate communication solutions within their existing software tools and other IT infrastructure.

In other words, UCaaS is a ready-to-use, all-in-one solution that is completely built and managed by a software vendor, while CPaaS is a communications API that requires programming expertise to integrate within existing software and infrastructure.

Session Initiation Protocol (SIP) trunking is a digital protocol for transferring voice calls and data over an internet connection. It is used by companies that want to leverage their existing phone systems and control their own PBX and internet telephony.
