All The Unified Comms Providers You Need To Know About

This guide contains an A-Z of all the unified comms providers you need to know about when selecting a new vendor for your communications estate.

Some of these unified comms providers also provide contact center solutions, some provide hardware as well as software, and some are niche to certain verticals and industries.

Find the right unified comms provider (or providers) for your business below.


1 - Avaya

Avaya is a long term provider of telecoms solutions


Avaya is a long-standing telecoms operator with a history in on-premises communications deployments. As Avaya moves into cloud communications, its focus is on migrating its existing client base onto its UCaaS platform.

In 2020, Avaya agreed to underpin its UCaaS offering with RingCentral’s VoIP. Avaya Cloud Office combines RingCentral’s platform with Avaya phones, services, and migration capabilities as a single solution.

2 - Cisco

Cisco provides the Webex collaboration platform


Having led the online meetings market for over a decade, Cisco recently merged its meetings, calling, and chat capabilities into a single unified Webex app. As a result, Gartner now recognizes Cisco as a leader for UCaaS. 

Formerly Jabber and then Webex Teams, Webex customers can schedule and launch meetings from the familiar interface while managing channel and direct messages from the same place.

Webex suits large-scale deployments with complex in-room and broadcast requirements.

3 - Dialpad

Dialpad is a pure cloud unified comms provider


Recognized by Gartner as a challenger in the UCaaS market, Dialpad provides a calling, messaging, and meeting platform influenced by AI. 

When acquiring TalkIQ, a real-time voice recognition platform, it added a differentiator to its portfolio. As such, Dialpad is a winner with call center agents who need to support back office interactions. The added agent assistance through AI provides coaching and sentiment analysis to ensure no upsell opportunity is missed and no customer goes unhappy.

4 - Google

Google provides unified comms as part of its Workspace solution


Google Workspace is commonplace in many small businesses and is a favorite with startups. But it’s also packed with UCaaS features ideal for enterprise collaboration. 

With several plans available including voice, chat, and meetings, businesses can choose from free access to basic functionality to a business plan with up to 500 video meeting participants and enterprise security eDiscovery and retention policies.

5 - GoTo

GoTo is now a unified comms provider

There is also a new addition of GoTo Connect which supports direct routing for Microsoft Teams; so you can use Teams as your interface and underpin it with GoTo’s VoIP calling.

Also provides: Contact Center | Conferencing | Remote Access


6 - Microsoft 

Microsoft provides Teams as its unified comms solution


A long-time leader of meetings and chat with Skype for Business, Microsoft Teams superseded this technology to add channel-based and asynchronous messaging.

Now with several options for calling (native, direct routing, operator connect), Microsoft can now consider itself a genuine UCaaS platform. In fact, Gartner recognized Microsoft as a leader in the 2022 Gartner Magic Quadrant for UCaaS.

7 - Mitel

Mitel offers both on-premises and cloud unified communications solutions


Mitel is one of the few unified comms providers that still provides an on-premises platform as well as a cloud version. It also maintains standalone options like MiTeam Meetings for those looking for a decoupled platform.

MiVoice Office delivers a basic version of phone system capabilities whereas MiCollab offers modern digital options like chat and channel-based collaboration.

Also provides: Contact Center | Mass Notifications Broadcast


8 - Nextiva

Nextiva is a pure cloud unified comms provider


Nextiva has a niche focus on small businesses looking for a quick setup and self-service UCaaS solution. But that’s not to say it’s lacking in features. Expect calling, chat, and meetings all built into a friendly interface with deep collaboration capabilities and integration options.

Nextiva provides two options for an integrated contact center: its own call center module and a unique cloud integration with Five9.

Also provides: Contact Center


9 - RingCentral

RingCentral is one of the unified comms providers you need to know about


RingCentral is the Gartner Magic Quadrant leader that stems from a core VoIP offering (as opposed to meetings like Cisco, Microsoft, Zoom). 

Having recently expanded its meetings, calling, and chat capabilities, RingCentral now includes optional add-ons for webinars, room systems, and customer experience. As a result, RingCentral has moved from a small business specialist to a genuine enterprise consideration.

  • Assisted living

  • Education

  • Finance 

  • Government

  • Healthcare

  • Manufacturing

  • Quick-service restaurants

Due to regulation, access, and pace of digital transformation, these industries are often the last to embrace modern communications technologies. Sangoma specializes in providing a gap solution as these businesses tread their path to the cloud.

11 - Vonage

Vonage is a unified comms provider now owned by Ericsson


Following key acquisitions of Nexmo and NewVoiceMedia in the 2010s, Vonage was acquired by communications equipment giant, Ericsson, in 2021. Rather than opting for a rebrand, Vonage lives on with a UCaaS solution offering chat, calling, and meetings from a single app.

Vonage also has key integrations with Microsoft Teams and Salesforce, recognizing the likelihood of target enterprise customers using at least one of these platforms.
