Orange Business Rainbow review
Rainbow combines IPBX telephony with messaging, meetings and sharing across cloud or hybrid deployments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Orange Business Rainbow is a cloud collaboration suite for organizations that want business telephony connected to an existing IPBX. It brings instant messaging and group chat together with audio and video calls, file sharing and storage, screen sharing, click-to-call, and an Outlook plug-in. Rainbow runs through web, Windows, macOS, iOS and Android applications, making it suitable for small, mid-market and enterprise teams that need communications across desktop and mobile devices.
The published plan material identifies an Essential free option alongside multiple subscription tiers. Rainbow is offered on a contact-sales basis, and the available capabilities and meeting limits vary by tier. That structure lets organizations match features to their needs, while teams evaluating paid plans will need a direct conversation with Orange Business. The free option provides an entry point for assessing the collaboration model before selecting a broader subscription.
Integration and deployment are Rainbow’s defining considerations. Its listed integrations are an IPBX and Microsoft Outlook, with click-to-call supporting telephony workflows and the Outlook plug-in fitting into email-based work. Orange Business describes cloud, hybrid and integrated deployment options, while associated Business Together Communications material supports hybrid and integrated modes. Orange experts provide implementation and support, and documentation is available as a support channel. Rainbow is a strong fit for teams standardizing messaging, meetings and file collaboration around an existing IPBX; organizations seeking a wide catalog of third-party integrations or a standalone communications service may prefer another platform.
