Features of a UCaaS Platform

UCaaS is a crucial building block for balanced productivity. Here are principal components to consider when choosing your UCaaS provider:


VoIP is king when it comes to unified communications. Cloud based telephony eliminates equipment connected to phone lines and allows companies to run phone systems using the internet. Unified communications provide many VoIP features including intelligent call routing, advanced call analytics, visual voicemail, and affordable international calls.

Audio/video conferencing

Video conferencing is an integral part of the post-pandemic workplace environment. It is a way to collaborate with colleagues without needing to be in the same physical space. Sharing files, providing presentations, and annotating content in real time from any device is the new normal.

Instant messaging and presence

Instant messaging within a UCaaS ecosystem replaces chatting with colleagues in the office. Moreover, a UCaaS platform allows for creating a dedicated room for any topic or project to keep communication organized and exchange files. Also, a UCaaS platform provide a user presence feature to display the status of colleagues.

Collaboration tools

Collaboration tools facilitate daily work. Calendar, file sharing, and project management features are crucial for any workflow.


Integration with existing business tools is a way to get the most from your UCaaS platform, enhancing the user experience. Some UCaaS solutions integrate with project management apps, workflow automation tools, and customer relationship management (CRM) systems.

Types of UCaaS architectures

Within unified communications, there are two primary architectures: single-tenancy and multi-tenancy. Each has its benefits, drawbacks, and requirements.

In a single-tenancy architecture, one customer uses a single instance of supporting infrastructure and software. In this architecture, the hosting provider manages the software instance and infrastructure but provides complete control to one tenant. The tenant can customize software and infrastructure as needed.

Single-tenancy is more secure and robust than multi-tenancy, as each customer’s data is stored separately from data of other customers. Also, one customer’s data isn’t affected if another customer’s software instance goes down. Meanwhile, single-tenancy is more expensive than multi-tenancy, since the costs of upgrading are placed on the customer. It also entails complex setup and management, especially when customizing a single-tenancy SaaS (software as a service) product.

Multi-tenancy is about sharing a single software platform. In this case, the software instance is hosted in the UCaaS provider’s data center. A multi-tenant architecture is a good fit for businesses with fewer hardware requirements. This type of architecture is an industry standard for enterprises.

Multi-tenancy is considered a more cost-effective solution with more support, lower maintenance costs, larger computing capacity, and more efficient resource use. Meanwhile, multi-tenant solutions are less flexible and customizable than single-tenant solutions. Some companies opt for a hybrid approach, keeping one part of their UCaaS platform on-premises (for management or security reasons) and moving other applications to the cloud.

UCaaS platform digital transformation enters the picture when modernizing on-premises communications software using cloud services. This way, companies can reinforce their position in the UCaaS market, boosting revenue and enlarging the customer base.

UCaaS: How does it work?

Features of a UCaaS Platform & Technology Trends

It’s impossible to talk about UCaaS and its nuts and bolts without talking about VoIP (Voice over Internet Protocol) phone service. VoIP transforms sound into data packets and transmits it to a cloud phone service provider. VoIP technology uses the universal Session Initiation Protocol (SIP), a signaling protocol for voice, video, and messaging applications.

UCaaS platforms usually have several key components:

  • Servers run by a unified communications provider, either located in their data center,. hosted in a third-party data center, or hosted on the public cloud (AWS, Microsoft Azure, Google Cloud)
  • Software clients, either downloaded on a device or accessed via a web browser using a plugin or WebRTC (Web Real-Time Communication) to stream audio and video
  • Endpoints (phones, whiteboards, and video conferencing tools) included in the UCaaS solution license cost or purchased separately
  • Public switched telephone network (PSTN) access, delivered by the UCaaS provider or integrated with the customer’s own Session Initiation Protocol services with the UCaaS platform (using the bring your carrier, or BYOC, approach)

You don’t need VoIP hardware to work with your customers, since having an internet connection is enough for accessing UCaaS solutions. Your employees can fulfill their tasks remotely by having a UCaaS platform on their devices. Simply put, unified communications replace massive and clumsy contact centers.

New technologies to upgrade your UCaaS platform

Future market insights expects the demand for UCaaS solutions to rise at 14.5% CAGR from 2021 to 2031, compared to the 10.7% CAGR we saw between 2016 and 2020. Following the trend of increased workspace digitization, unified communications will see even more significant changes with the adoption of 5G and artificial intelligence solutions.

Artificial intelligence (AI) and machine learning (ML)

Artificial intelligence (AI) is already widely used to automate routine communication processes. However, AI will elevate UCaaS systems further. We have seen recent improvements in priority-setting technology, meeting aids, and virtual assistants.

UCaaS solution providers have adopted augmented reality (AR) and AI to facilitate remote teams, reducing dependence on in-office teams. This trend enables the development of new UCaaS features including voice intelligence (VI), live call sentiment analysis, and post-call summaries.

5G to impact UCaaS security and reliability

By the end of 2027, 5G subscriptions will reach 48% of global mobile subscriptions, bringing more revenue for various verticals, including UCaaS. 5G is perfect for keeping remote and hybrid employees connected, improving network connectivity and increasing work-from-anywhere productivity.

Moreover, 5G is underpinned by IMSI (International Mobile Subscriber Identity) e2e encryption, making UCaaS solutions secure. Enterprise-wide network security remains a crucial factor in post-pandemic remote work settings.
