Best UCaaS Platforms

UCaaS, or unified communications as a service, software serves as a communication and collaboration hub for organizations. These tools provide features such as VoIP, instant messaging, video conferencing, and other collaboration tools in a singular, cloud-based platform. UCaaS platforms can connect entire enterprise businesses, facilitating rapid, streamlined communication and decision-making with varying functionality offered in one product. While the U in UCaaS stands for unified, not universal, the goal of these platforms is to bring all corporate person-to-person communication methods under one umbrella.

UCaaS products offer features provided by collaborative point solutions such as VoIP software, video conferencing software, internal communications software, and other team collaboration software types. While businesses could purchase each one of these solutions separately, a UCaaS platform can potentially supply the features of them all in a more malleable package. The integrated nature of these platforms enables users to monitor and receive alerts via one medium.

While UCaaS products provide extensive functionality themselves, many will integrate with outside content management systems or contact center software depending on the specific use case of the organization in question. However, it is extremely uncommon for UCaaS to provide discrete email capabilities, and typically leverages whatever email system the business uses to handle messaging and coordination in that channel.

To qualify for inclusion in the UCaaS category, a product must:

Be a cloud-based collaboration and communication platform
Supply VoIP, video conferencing, business messaging, and file sharing
Provide cross-channel functionality
Offer additional collaboration and communication tools natively
Be flexible enough to incorporate new communication channels as they are developed

Learn More About UCaaS Platforms

What are UCaaS Platforms?

UCaaS stands for unified communication as a service and is a type of software as a service (SaaS) that provides multiple channels for communication in one platform. UCaaS platforms will offer communication channels such as instant messaging, VoIP, and video conferencing with a number of other cherry-picked collaboration tools like screen sharing, whiteboarding, and file sharing. UCaaS tools are also notable because the features provided by the platform are available on multiple devices. Users can easily access communication tools provided from desktops, laptops, mobile phones, and proprietary hardware if a service provides it.

Businesses have been leveraging unified communications (UC) systems for decades, but these older solutions required extensive hardware setup and maintenance. The IT support required to maintain these on-premises solutions was expensive and demanding on manpower. UCaaS brings UC into the future by offering all the functionality buyers are looking for in a service conveniently hosted in the cloud. The pay-as-you-go model that comes with a cloud-based solution has driven down the cost for unified communications, which has made them more widely available to nonenterprise companies.

Key Benefits of UCaaS Platforms

  • Bundles multiple communication channels into a singular platform and offering
  • Allows for seamless movement between communication channels
  • Available across multiple devices
  • Provides additional native collaboration tools
  • Combines internal and external communication channels

Why Use UCaaS Platforms?

Businesses often find point solutions for each of the communication channels they want covered. This means one product for VoIP, another for business messaging, and one more for video conferencing. That also doesn’t include all the other productivity and collaboration tools teams use in conjunction with these channels. A UCaaS solution bundles all these communication channels and productivity tools into a single offering, which provides multiple benefits.

Savings — When a business covers all their communication channels with point solutions, the cost of licenses and monthly payments adds up, especially for small and mid-market businesses. A UCaaS solution can bundle all communication channels, internal and external, into one platform for a business to pay for. While the initial price tag of a UCaaS product could potentially be high, the cost could be the same or higher when paying for several disparate solutions across months or years. Additionally, UCaaS customers can choose an option that allows them to only pay for the channels and features they want or a scaled-down out-of-the-box solution to save money as well.

Increased efficiency — One issue with point solution communication solutions is there isn’t a guarantee that they will integrate with one another. A conversation happening via instant messaging might become one that is better over a video feed. If a team only has point solutions to choose from, they will have to move to another application to continue, which may or may not be an easy transition. Even worse, the conversation may be put off entirely. This is especially necessary for sales or help desk representatives speaking to customers or clients in one channel that need to continue in another. When teams use UCaaS, they can move between different communication channels without leaving the application itself, streamlining conversations and ensuring users have access to the channel they need when they need it.

Enhanced collaboration potential — While businesses have the option to use point solutions for communication and collaboration, it’s a toss up whether those solutions integrate with one another. If they don’t, it can be problematic if users need to use multiple solutions during a conference call or collaboration session. UCaaS products easily allow teams to use collaboration tools alongside conferencing solutions simultaneously, which bolsters fruitful brainstorming sessions and meaningful conversations.

Who Uses UCaaS Platforms?

The beauty of UCaaS is that it’s universally helpful regardless of industry. The need for meaningful communication and collaboration is a necessity in every business. While larger businesses in the mid-market and enterprise levels arguably benefit more from comprehensive communication coverage, small businesses can still find boons in the breadth of collaboration tools provided by UCaaS. However, the potentially high price tag attached to a UCaaS will often make it a better choice for mid-market and enterprise organizations, and small businesses can easily have their collaboration and communications needs fulfilled by cheaper point solutions.

Kinds of UCaaS Platforms

There are two main distinctions buyers can make when looking for UCaaS products: internal versus external use and customizability. While some UCaaS systems can be used for both internal and external communications, many are specific to internal or external use cases. Additionally, customizability is determined if the UCaaS in question is a built-to-order, single-tenant system or an out-of-the-box, multi-tenant system.

Internal use — UCaaS products that support internal communications will provide collaboration tools, like whiteboarding and instant messaging, on top of the VoIP and video conferencing features buyers expect. Internal-facing UCaaS products will provide integrations with content management solutions to ease file sharing and storage needs.

External use — UCaaS for external use will serve as the backbone for call center infrastructure. Call center representatives will have multiple communication channels to leverage when interacting with customers, and UCaaS systems conforming to this use case will provide integrations with help desk software to assist with ticketing and obtaining customer information.

Single-tenant systems — A single-tenant system is built for a specific client by a UCaaS provider. Companies can pick and choose the functionality and integrations they require out of their UCaaS, ensuring they only pay for the features they need. Single-tenant systems are a great option for companies with specific needs, like particular APIs or less extensive offerings for a small business. Single-tenant systems can potentially be very expensive, however. A UCaaS provider may charge extra to develop a tool with all the functionality a business wants. If a business wants an enterprise-level custom product, they can expect a price tag that reflects that functionality accordingly.

Multi-tenant systems — Multi-tenant systems are generalized, out-of-the-box UCaaS products intended for use by multiple organizations. These offerings come as they are and have comparatively less customization options for businesses. Businesses looking for a UCaaS system they can simply deploy and maintain may stand to save money by choosing a multi-tenant system if they don’t require any specific integrations or APIs.

UCaaS Platforms Features

A UCaaS product is a bundle of communication channels loaded into one offering, so the features of a typical UCaaS product often look like a list of point solutions. UCaaS products can vary in what channels they provide and the other collaboration tools they feature. Listed below are many of the popular features offered by UCaaS solutions, but this list is by no means exhaustive.

Instant messaging — One of the basic features of a UCaaS is 1:1 and group instant messaging. Users have the ability to either message each other directly or send messages to a group.

VoIP conferencing — Audio conferencing in UCaaS products is provided via voice over internet protocol (VoIP). Users can access VoIP-based phone systems or audio conferencing over other devices.

Video conferencing — Another stable feature of UCaaS is video-based conferencing. The audio component of the video feed is hosted via VoIP.

Screen sharing — Any UCaaS that provides video conferencing will also provide screen sharing. Users can easily share a live feed of their screen or of a specific program.

File sharing — Users have the ability to share files with one another using a UCaaS platform. Some UCaaS products will streamline document and content sharing by integrating directly with content management systems.

Additional UCaaS Platforms Features

Whiteboard — UCaaS products that heavily emphasize internal collaboration will often natively provide a collaborative whiteboard software within the platform. Teams can use the whiteboard during in-person meetings or web conferencing.

Automated attendant — An automated attendant automatically routes calls throughout an enterprise. This is especially useful for companies that require an expansive PBX phone system.

Voicemail to email — One benefit of UCaaS is the unified nature of the communication channels provided by the platform. Users can receive voicemails via email since phone calls are hosted over VoIP.

Voicemail transcription — Some UCaaS solutions can transcribe voicemails into text-based messages that are easier to store and keep track of compared to audio files.
