Rainbow 2.165.3.0, published by ALE International, is a cloud-native communication and collaboration platform engineered for professional environments that require secure, carrier-grade voice, video, messaging, and file-sharing from any location or device. Positioned within the unified communications and team collaboration category, the software consolidates PBX calling, multi-party HD video conferencing, persistent chat rooms, screen and document sharing, presence, and business-process connectors into a single interface, eliminating the need for separate telephony, meeting, and chat tools. Typical use cases include remote and hybrid workforces that must maintain enterprise telephony features while adding modern team collaboration; project teams that need always-on virtual rooms with searchable history and integrated task boards; customer-support groups leveraging click-to-call from CRM records; and partners or suppliers that require temporary, policy-governed guest access to shared spaces. The client is released in three concurrent versions—desktop, mobile, and web—each updated in parallel so that field workers on smartphones, office staff on Windows or macOS, and external guests on browsers all share identical capabilities and security baselines. Session continuity allows a call started on a desk phone to be transferred seamlessly to a laptop or mobile headset without interruption, while end-to-end TLS and SRTP encryption, GDPR and ISO 27001 compliance, and optional on-premises media nodes address regulated-industry requirements. Rainbow is available for free on get.nero.com, with downloads supplied through trusted Windows package sources such as winget, always providing the latest release and supporting batch installation alongside other applications.
