Alcatel-Lucent Enterprise Rainbow is a cloud communication and collaboration platform for businesses and public organizations. It brings persistent one-to-one and group chat, audio and video calling, meetings, screen and application sharing, file sharing, presence, contact management, and business telephony into one service. Teams can access it through web, Windows, macOS, iOS, and Android applications. Rainbow can connect with existing PBX systems and supports public, private, hybrid, or on-premises deployment models, making it relevant to organizations with varied communication environments.
The published plans range from the free Essential tier to paid options for business communication, collaboration, conferencing, storage, and telephony. Essential is a free service for individual use with messaging, voice and video calls, screen sharing, and file sharing. Business adds business communication and collaboration services through a per-user subscription. Enterprise adds multi-party collaboration, video conferencing, and extended file storage, while Enterprise Dial-In Pack adds unlimited phone conferencing minutes.

APIs and SDKs are available through Rainbow CPaaS for embedding communications into applications and workflows. The platform also includes call recording on supported plans and video meetings with up to 120 participants on supported plans.
