What happened to Mitel’s UCaaS business?

Mitel previously offered several Unified Communications as-a-Service (UCaaS) products as part of its portfolio. In 2021, Mitel made the decision to transition from operating its own UCaaS products to working with leading UCaaS to support customers who prefer a pure UCaaS model.

Through this process, Mitel’s legacy UCaaS products have been retired or acquired, allowing Mitel to focus on delivery of its core UC (private cloud, hybrid cloud, and on-premise) solutions.

What happened to MiCloud Connect?


MiCloud Connect is a former UCaaS platform that was rebranded by Mitel after the 2017 acquisition of ShoreTel and is End of Sale. It was acquired by RingCentral in 2024 and is now branded MiCloud by RingCentral. Details about the transition for existing MiCloud customers can be found on the RingCentral web site.


What happened to Sky / ShoreTel Sky?


Sky (aka ShoreTel Sky) is a former UCaaS platform from Mitel’s 2017 acquisition of ShoreTel and is End of Sale. It was acquired by RingCentral in 2024 and is now branded Sky by RingCentral. Details about the transition for existing Sky customers can be found on the RingCentral web site.


What happened to Unify Office & Unify Video?


Unify Office & Video are no longer being sold by Mitel. Existing Unify Office & Unify Video customers are being supported by RingCentral.


Can I still purchase a UCaaS / pure cloud solution from Mitel?


Mitel no longer sells its own pure UCaaS (public cloud) solutions. Additionally, Mitel’s previous programs to migrate Mitel customers on legacy UCaaS platforms to RingCentral are no longer active. Mitel does support integrations with various UCaaS vendor platforms.


Looking for an alternative solution with Mitel?


Mitel offers flexible hybrid cloud (mix of UCaaS and private cloud/on-prem), private cloud, and on-premises platforms that can be licensed as a subscription or one-time purchase based on your organization’s needs.
