Magic Quadrant for Unified Communications as a Service, Worldwide
Published 12 November 2020 - ID G00448214 - 46 min read
Strategic Planning Assumptions
Market Definition/Description
- Telephony: This includes enterprise telephony capabilities and, often, PSTN access. Providers that do not provide PSTN access have a “bring your own PSTN provider” strategy. Telephony services are used by people with either physical phones or software clients (desktop clients, web clients or mobile apps). Telephony also includes unified messaging and voicemail services.
- Meetings: This area includes multiparty audio/videoconferencing with content sharing (screen and application sharing) and in-meeting messaging and file-sharing capabilities. Gartner’s definition of meetings for the UCaaS market limits capabilities to standard business meeting use cases — it excludes specialized use cases such as webinars, IT support and remote education.
- Messaging: Messaging capabilities enable users to exchange text messages and other information in real time. They have evolved to include two main modes: personal messaging for one-to-one communication and team messaging for the exchange of messages within groups or teams using conversational user experiences. Presence capabilities enable users to see the availability, location and other contextual status information of other users and resources. Some UCaaS providers have extended messaging to include integration of their desktop clients and mobile apps with SMS/MMS services, as well as with consumer messaging services like iMessage, WhatsApp and Facebook Messenger.
- Mobility and software clients: Software clients enable access to multiple communications functions from a consistent user experience. UCaaS providers offer desktop clients, web clients, mobile clients for smartphones and tablets, as well as software extensions and plug-ins that integrate with business applications such as calendars and email clients.
- Communications-enabled business processes: This area includes the ability to integrate discrete UC capabilities with other business and communication applications. Integrating communications within the context of other business applications offers significant value. Integration options include contact centers, collaboration and ChatOps/workgroup applications, workstream collaboration, plug-in integrations for leading cloud business applications, communications platform as a service (cPaaS) for digital business application integrations, and integration with business analytics and artificial intelligence (AI).

Vendor Strengths and Cautions
8x8
- 8x8 has a broad range of natively developed and integrated telephony, meeting solution and contact center capabilities that can meet most requirements of small, midsize and large businesses.
- 8x8’s adjacent cPaaS capabilities enable customers to develop customized, industry-specific SMS, chat, text-to-speech and video-enabled communications use cases.
- 8x8’s growing focus on channel enablement — it has launched a new partner program and portal — and value-added reseller relationships (through its CloudFuel partnership with ScanSource) boost its ability to scale its business.
- 8x8’s platform offers PSTN support in 41 countries. 8x8 has operations across North America, Europe, Asia/Pacific and Latin America.
- 8x8’s entry-level customer support can be slow to resolve issues. Customer feedback indicates that escalation to specialists may be required.
- 8x8 Meet is a new meeting solution with capabilities including support for a maximum of 100 participants. However, 8x8 Meet does not yet support some advanced features, such as whiteboarding and polling.
- Although 8x8 offers both contact center and meeting solutions, their functionality might be insufficient for some use cases with extensive feature requirements.
- 8x8’s brand is less well-recognized than those of some of its UCaaS competitors. Also, 8x8 has not developed strategic partnerships with legacy telephony providers, which reduces its chances of consideration by organizations transitioning from premises-based UC.
Alcatel-Lucent Enterprise
- ALE’s Rainbow service is a global offering that has achieved early penetration of Asia/Pacific and Western Europe. It supports 19 languages.
- The open architecture of ALE’s Rainbow service enables partners and customers to build customized vertical solutions and value-added services. Prebuilt, off-the-shelf applications are also available in the Rainbow store.
- ALE’s Rainbow technology and business model differ from those of competitors by focusing on best-of-breed third-party application integrations via APIs and cPaaS connected by the Rainbow API Hub.
- ALE’s Rainbow service offers a dedicated private cloud deployment option for organizations that cannot use multitenant public cloud UC.
- ALE lacks a native preintegrated telephony capability. Furthermore, ALE is still only in the early stages of a partnership with RingCentral to position Rainbow Office powered by RingCentral.
- ALE’s meeting capability is best suited to internal collaboration between small groups. It is limited to 120 participants and lacks features generally expected for more formal use cases.
- ALE’s Rainbow strategy relies heavily on partners to fulfill customer requirements. This adds complexity, as well as the risk of its offering being less consistent than those of competitors.
- Rainbow’s availability SLA target is 99.5%, which is significantly lower than those of competitors. Also, ALE does not offer credits to customers if it fails to meet SLA targets.
Cisco
- Cisco has a strong brand and deep CIO relationships across the globe. Its UCaaS portfolio is complemented by Wi-Fi, LAN, WAN, SD-WAN, security and data center assets.
- The number of inquiries about Cisco received by Gartner’s client inquiry service rose, year over year, by 70% in the first three quarters of 2020, which suggests increased interest in this vendor.
- Cisco delivers a comprehensive suite of UCaaS services via a global platform and a unified Webex app that supports meetings, calling and messaging with an integrated device portfolio. Customers generally view Cisco’s portfolio of video room and personal collaboration devices positively.
- Cisco has a large, diversified and global set of channel partners capable of selling to businesses of all sizes.
- Gartner clients that are migrating from existing premises-based Cisco solutions report that they struggle to decide between Cisco’s various cloud UCaaS offerings, which include Webex, Hosted Collaboration Solution (HCS) and Cisco Unified Communications Manager Cloud (UCMC).
- In the past year, Cisco has made significant changes to its senior leadership across its UCaaS and contact center as a service (CCaaS) portfolios.
- Different channel partners offer different Cisco UCaaS options. Many continue to promote Cisco HCS options based on older architectures, which may not benefit from some of Cisco’s latest innovations for the Webex portfolio.
- Cisco is losing UCaaS mind share to Microsoft, RingCentral and Zoom. These competing vendors are each focused on a single cloud UC platform.
Dialpad
- Dialpad continues to innovate and expand its “Voice Intelligence” capabilities for AI and voice analytics across its portfolio.
- Nearly all of Dialpad’s customers can activate their service without any on-site support. Dialpad offers various professional services packages for onboarding, implementation, network assessment, device provisioning and training.
- Dialpad’s partnership with Google provides telephony to Google G Suite customers. Dialpad’s UCaaS solution is available from the G Suite Marketplace, and a Chromebook app is now available.
- Gartner clients continue to report good customer service and support from Dialpad.
- Dialpad pays more attention to voice than to other parts of its UC stack.
- Dialpad UberConference lacks some basic meeting features, such as a lobby, the ability to switch audio during meetings, closed captioning, private messaging and polling. It has more limitations than solutions included in competing UCaaS offers.
- Dialpad’s Android and iOS mobile clients lack team messaging, video and screen-sharing capabilities.
- Dialpad is a relatively small provider with limited market visibility. Its business is skewed toward English-speaking markets, although support for additional languages has been added in the past year.
Fuze
- Fuze now sells only to large organizations with more than 500 users, including multinationals. This change in strategy enables Fuze to focus its resources on fewer organizations, while delivering more professional services. Fuze has hundreds of customers in more than one region of the world.
- Gartner clients have praised the design of the user interface and user experience of the Fuze desktop and its mobile apps.
- Fuze can deliver “full PSTN replacement” services in 35 countries, 21 of which are in Europe and seven in Asia/Pacific.
- Fuze has significantly improved the capabilities and desktop user experience of Fuze Contact Center. This tightly integrated contact center solution enables users with UC and contact center requirements to obtain comprehensive services from a single, unified platform. Recent Fuze Contact Center enhancements include an improved user experience and more extensive capabilities.
- As Fuze has shifted its focus to large organizations, it is no longer well-suited to organizations with fewer than 500 users.
- Fuze has had significant changes of executive leadership in the past 12 months. The current executive lineup has itself made bold changes, such as the move to focus exclusively on the enterprise segment.
- Fuze’s brand profile remains low, judging by the company’s recognition by Gartner clients. Large organizations may be unaware that Fuze could be a good option for them.
- Select Gartner clients have reported that resolution times for incidents involving NICE inContact contact centers could be improved.
- The integration of Google Voice, Meet and Chat into Gmail gives G Suite users easier access to UC features and promotes adoption.
- During the past year, Google has added many new end-user functional features, performance improvements and security features to its UCaaS offering.
- Access to the Google Jamboard app on any device provides easy access to virtual whiteboarding functionality for the “anywhere” workforce.
- Google has a consumer-friendly user experience design, one focused on ease of use. It is well-received by users.
- Despite reports of strong adoption of Google Voice, Google has been slow to expand the geographic reach and availability of this service. Although Google supports calling plans in 11 countries, no new countries were added in the past year. Support for Google Voice in Japan is expected by 2021, however.
- Google’s availability SLA target for all G Suite services, including Meet, Chat and Google Voice, is 99.9%, which is considerably lower than most UCaaS competitors.
- Google’s telephony capabilities will satisfy the needs of organizations that require only a basic feature set, but not for those that require an extensive set of advanced telephony features.
- Google supports only a small number of desk phones, from Poly.
LogMeIn
- LogMeIn has a long track record, having provided cloud-based meeting solutions for over 15 years, including through its GoToMeeting service.
- LogMeIn’s meeting capabilities are extensive, mature and especially capable for external participants. The new desktop and mobile client user experiences are well-designed and intuitive.
- LogMeIn prices GoToConnect competitively, relative to other offerings with similar capabilities.
- LogMeIn has a significant number of complementary cloud-based services, such as GoToMeeting and GoToWebinar.
- LogMeIn’s UCaaS customer base is almost entirely in the U.S. Full PSTN replacement capabilities are available in nine countries outside the U.S., however. Large and highly multinational organizations should confirm that LogMeIn can deliver UCaaS to the regions and countries where they operate.
- Forty-three percent of LogMeIn customers are small (with under 100 users), and 23% are midsize (under 1,000 users). Forty-two percent of LogMeIn’s customer base procures services on a month-to-month basis. Large organizations should ask for comparable references.
- GoToConnect does not yet support team messaging, and the mobile app does not support personal messaging (chat). These capabilities are, however, on LogMeIn’s roadmap. Organizations planning to rely heavily on the messaging capabilities inherent to a UCaaS offering should check their availability with GoToConnect.
- LogMeIn does not yet support virtual desktop (VDI) environments with itsGoToConnect desktop client.
Microsoft
- Microsoft’s enterprise license agreement, which entitles users to Microsoft Teams, is a strong influence on organizations considering UCaaS. The majority of Gartner clients, which are midsize and large organizations, have Microsoft enterprise license agreements in place.
- Microsoft Teams has the most complete set of integrations with Microsoft’s Office 365 services and applications. Microsoft Teams is itself “built” from many Office 365 services and applications, such as Azure Active Directory, SharePoint, OneDrive and Exchange Online.
- Microsoft’s collaboration features for messaging and meetings fully satisfy a significant percentage of the user base in organizations that want to add enterprise telephony at a low additional cost to that of an E1 or E3 license.
- Most Gartner clients already use Microsoft Teams for messaging and meetings, and they report good or better levels of satisfaction. Adoption has increased in response to COVID-19. End users’ familiarity with Microsoft Teams for messaging and meetings has led to end-user demand for IT organizations to add telephony.
- Microsoft’s telephony capabilities are good enough for many organizations, but not for those that require advanced telephony features. Furthermore, Microsoft’s availability SLA target of 99.9% is considerably lower than that of most UCaaS competitors.
- Microsoft is not currently a suitable option for organizations that require contact center capabilities delivered from the same platform as UCaaS services.
- The price of Microsoft’s calling plans remains notably higher than those of PSTN providers. Also, the number of countries in which Microsoft supports calling plans is limited. Microsoft supports 11 countries, whereas most UCaaS providers and telecom operators typically support 30 or more. For these reasons, large organizations that use Microsoft for UCaaS almost always require a separate PSTN provider.
- Gartner clients are often unfamiliar with which Microsoft implementation partners to use, and the price of these partners’ professional services varies widely, which makes it challenging for buyers.
Mitel
- Mitel has invested in partner enablement resources (from lead registration to customized sales and marketing resources) to improve its support for partners. Mitel’s channel practice accounts for a growing percentage of its sales.
- Mitel’s premises-based MiVoice Connect on-site solution has the same user experience as MiCloud Connect, so customers migrating from it to the cloud will be familiar with the user experience.
- Mitel has recommitted itself to supporting the adjacent MiCloud Flex solution and to creating cloud delivery options for organizations that require more customization and control. MiCloud Flex has a broader service delivery footprint and is now also available via select partners as a managed service.
- Prices for Mitel’s MiCloud Connect are lower than those for many competing offerings, which makes it attractive for businesses heavily influenced by cost pressure.
- Mitel’s UCaaS delivery reach is limited. MiCloud Connect, with full emergency support, is currently available only in North America, Australia and the U.K. Mitel’s geographic expansion plans continue to face delays.
- Mitel’s MiTeam Meetings solution is immature and has some feature limitations. It does not yet offer mobile or web support (it is limited to desktop support). It is limited in terms of scalability (100 users maximum) and video (16 users maximum), and it does not support room systems. Calendar integration is planned for release during the second half of 2020.
- Mitel’s MiCloud Connect is increasingly popular with SMBs, but large organizations should check that Mitel’s feature capabilities and product support meet their requirements.
- Mitel uses the public Google Cloud for UCaaS, but some organizations have sensitive requirements that prohibit the use of applications hosted on public infrastructure.
RingCentral
- RingCentral has continued to improve in several key areas, including product development and capabilities, sales and distribution, global coverage, and customer service and support.
- RingCentral now has a self-developed meeting solution that gives it full control over its roadmap and capabilities, because it no longer relies solely on Zoom. RingCentral Video is API-enabled and can be used for integrations in the healthcare and education sectors.
- RingCentral has improved in terms of regulatory compliance. It now supports Germany’s Cloud Computing Compliance Controls Catalog (C5) data residency standard, the U.K. Cyber Essentials security scheme, and STIR/SHAKEN protocols and procedures for caller ID authentication. This enables RingCentral to enter new markets that it would previously have found challenging.
- RingCentral’s support organization has a core competency in contact centers, including the NICE inContact CCaaS solution, as well as RingCentral’s internal CCaaS solutions, which are well-suited to relatively small organizations.
- RingCentral’s focus on strategic partnerships, and especially on developing compatibility with partners’ phones, gateways and legacy UC infrastructure, may prevent it from devoting all its R&D resources to innovation.
- Although RingCentral’s partnership with NICE inContact has benefits, it also means RingCentral depends on a partner for an important component of its offering and does not fully control the roadmap for the contact center.
- RingCentral’s licensing is not as flexible as that of some competitors because it requires selection of a single seat type for an entire organization. Competitors allow mixing and matching of seat types.
- RingCentral Video is new and requires the closure of functional gaps for the meeting use case — for example, with regard to webinars and room meetings. There are also functional gaps relating to the premeeting, in-meeting, postmeeting, mobility and meeting-room capabilities available with RingCentral Meetings.
Star2Star
- Customers find Star2Star’s UCaaS and its new cPaaS offering to be cost-effective, and they consider that both deliver value. The cPaaS offering includes bundled applications such as Employee Alerts, Urgent Notification and Mass Notification.
- Star2Star has enhanced its contact center capabilities to improve their suitability for customers with midrange UCaaS and CCaaS requirements. Star2Star has consistently made significant improvements to its contact center offering over the past three years, and has prioritized these enhancements on the basis of market feedback.
- The Star2Star platform has embedded self-developed SD-WAN capability with 4G/LTE backup for improved service reliability. This offering is ideally suited to the needs of highly distributed organizations that have many small locations or stores and that want improved reliability.
- Star2Star has continued to enhance its quoting engine, RocketQuote, which now supports digital signage, to improve the speed and agility of the sales process.
- The 1Q20 divestiture of UCaaS provider Blueface (to Comcast) reduces Star2Star’s visibility in, and coverage of, European and Asia/Pacific markets.
- Organizations that choose Star2Star and require support for extensive meeting use cases (such as webinars, remote learning and large all-hands meetings) will need supplementary third-party solutions.
- Star2Star’s brand is not well-known. Given its focus on indirect sales, Star2Star has not invested in building its brand with end customers. Most Star2Star channels offer its product on a white-label basis.
- The software clients (desktop and web) and mobile apps of Star2Star’s leading competitors have more extensive capabilities for meetings and messaging. This is significant because the user experience and capabilities of software clients are increasingly important factors for vendor selection.
Vonage
- Vonage takes a cloud-native platform approach in which capabilities are built on top of APIs. This approach fosters agility and flexibility in terms of bringing new capabilities to market and enabling application development.
- Vonage has tight contact center-CRM integration with the VBC UCaaS solution. Customers with contact center and UC requirements can benefit from single sign-on, a single presence and a common UI for smooth navigation between solutions.
- Customers generally report that Vonage’s customer support team is responsive and handles issues in a timely manner.
- Vonage differentiates itself through application integrations. It promotes (1) integrations with Zapier, an integration platform as a service (iPaaS) provider, to enable common app integration without the need for developer resources; (2) the Vonage App Center, which enables partners to create embedded integrations; (3) Vonage Smart Numbers, which supports customization with minimal coding requirements.
- Vonage’s geographic footprint for UCaaS may not meet the requirements of organizations headquartered outside North America, or those that have headquarters in North America and branch offices across the world.
- Vonage Meetings is a new offering with emerging capabilities. It currently supports up to 100 participants (with a maximum of 16 video participants). It does not currently support integration with room video systems.
- Vonage typically serves small and midsize organizations. Its onboarding and support teams are not as experienced at serving large enterprises with complex requirements.
- Although Vonage offers configuration flexibility to support unique use cases, its solution positioning does not emphasize deep industry-specific capabilities upfront.
Windstream
- Windstream offers several options for UCaaS and CCaaS, which can be combined to suit most organizations’ use cases.
- Optional bundles for network access, SD-WAN and professional services enable Windstream to serve as a “one-stop shop” for some organizations.
- Windstream provides a unified portal, WE Connect, for network and device monitoring, call quality analytics, availability monitoring and system administration. WE Connect is accessible from a web or mobile client, which enables administrators to be more mobile.
- Windstream has a strong industry focus, with multisite customers in the finance, healthcare, retail and education sectors.
- Windstream has just emerged from Chapter 11 bankruptcy protection.
- Windstream’s geographic presence is limited, compared with that of other providers in this Magic Quadrant. The company relies on partners to support all customers outside the U.S. and Canada.
- Windstream OfficeSuite HD Meeting, powered by Zoom, does not currently offer native support for Zoom Rooms.
- Windstream is not well-known in the UCaaS market. We see limited interest in Windstream’s UCaaS offering among Gartner clients.
Zoom
- For organizations already using Zoom Meetings, Zoom Phone Basic is available at no additional charge (without PSTN access). This is a major attraction for organizations looking to add telephony from a single vendor cost-effectively.
- Despite the Zoom Phone service being relatively new, it offers a 99.999% availability SLA target.
- Customers generally praise Zoom Meetings for its ease of use, service reliability, and pace of innovation and enhancement.
- Zoom has significantly raised its profile during the COVID-19 pandemic by bridging the gap between consumers and enterprises with “freemium” packages and by offering incentives to organizations signing up to Zoom for the first time.
- Zoom Phone offers a basic set of enterprise telephony features. Organizations currently using on-premises solutions and seeking a UCaaS provider with an advanced set of telephony features may find gaps.
- Zoom calling plans are available in only 42 countries and territories. Zoom does offer a “bring your own carrier” option, which adds flexibility, but it requires additional effort to configure.
- Zoom does not offer contact center functionality, so it is unsuitable for organizations that want UCaaS and CCaaS delivered from a single platform. Zoom does, however, partner with leading contact center providers, and its offering can be integrated with Five9, Genesys, NICE inContact, Talkdesk and Twilio.
- Some Gartner SMB clients who use Zoom have reported delays in support and relatively unresponsive account management.

Market Overview
- Team messaging and SMS: UCaaS providers have extended the capabilities of team messaging and workstream collaboration services by integrating business applications, integrating file-sharing services, adding bot frameworks, and providing connectivity to mobile SMS messaging from desktops, web clients and mobile apps.
- Meetings: The meeting capabilities included in UCaaS solutions have steadily improved and have partially converged with those of stand-alone cloud-based meeting solutions. Many UCaaS providers are also meeting solution providers.
- APIs, cPaaS and app marketplaces: Integration of UC capabilities with applications that support broad workflows and business applications brings significant value. Examples of such integration include CRM applications, contact centers, workgroup applications and line-of-business applications. Some UCaaS providers have extended their offerings to include cPaaS, which enables the consumption of “atomized” capabilities (for example, the ability to send an SMS or initiate a call) by other applications that are enhanced by integrating and enabling communication services.
- Reporting and analytics dashboards: UCaaS offerings provide administrative tools that visualize availability, failures, performance, diagnostics, usage, user adoption and other key performance indicators. Dashboard reporting can be measured and displayed on multiple levels, such as call, user, business unit and location.
