What Happened to Atos Unify
Unify — the enterprise communications division of Atos SE, known for its OpenScape platform — was acquired by Mitel Networks Corporation in October 2023. The acquisition combined Mitel’s existing UC portfolio (MiVoice, MiContact Center) with Unify’s OpenScape product line, creating what the companies describe as the second-largest global enterprise unified communications provider. The combined entity serves over 75 million users across 100 countries.
For existing OpenScape customers and channel partners, the key takeaway is that OpenScape products continue under Mitel’s ownership with ongoing support, maintenance, and roadmap commitments through 2025 and 2026. However, software support for OpenScape Business systems with V2 mainboards ends in 2026, which will drive migration conversations for affected customers.
OpenScape Product Line Under Mitel
The OpenScape portfolio now sits within Mitel’s broader product family. OpenScape Voice is the large-enterprise IP telephony platform supporting thousands of users per deployment. OpenScape Business serves small and medium enterprises with an all-in-one unified communications system. Both platforms continue to receive updates and are part of Mitel’s hybrid communications strategy — supporting on-premise, cloud, and hybrid deployment models.
Mitel-Zoom Strategic Partnership
In September 2024, Mitel and Zoom announced a strategic partnership to deliver a hybrid cloud solution combining Zoom Workplace (including Zoom AI Companion) with Mitel’s on-premise platforms. The global rollout began in February 2025, starting with OpenScape Voice and OpenScape 4000, expanding to MiVoice Business, MiVoice 5000, and MX-ONE platforms through 2025.
This partnership is significant because it allows enterprises with existing Mitel/OpenScape on-premise PBX investments to add Zoom’s cloud collaboration capabilities without ripping out their telephony infrastructure. Zoom Workplace provides the collaboration layer (meetings, chat, AI features) while Mitel’s platform continues handling call control and PSTN connectivity — a practical hybrid approach for organisations not ready for a full cloud migration.
Why SA Resellers Should Know About This
South Africa has an installed base of Unify/OpenScape systems, particularly in larger enterprises and government organisations that deployed these platforms during the Siemens and Atos eras. Resellers serving these customers need to understand that OpenScape is now under Mitel’s umbrella, with Mitel managing the product roadmap, support, and partner programme.
The V2 mainboard end-of-support in 2026 creates a specific migration opportunity — affected customers will need to upgrade hardware or move to newer platforms. The Mitel-Zoom hybrid option provides a migration path that preserves existing on-premise investment while adding modern collaboration capabilities. For resellers, this means understanding both the Mitel product roadmap and the Zoom partnership is essential for advising OpenScape customers on their next steps.
