It’s never been as easy to efficiently work from anywhere you want to, be it the office, at home, or on the road. And because you should be able to clearly delineate when you are at work, instead of mixing your private and professional life, take control of your availability and which phone numbers you want to share.


From changing your welcome message to advertise new products, over updating your calendar to organise an open day to creating an account for an internship – all this is made possible by using a simple web administration interface. Stay in control of your communications and on top of day-to-day business anywhere.


Because your communications matter, Alcatel-Lucent Enterprise, with its long history in telecommunications, leverages what is its DNA to build smart technologies, design simple and efficient processes and employ highly skilled and passionate people to deliver a reliable, secure and truly sovereign service.

Routing presets

Each user may configure routines and have Rainbow manage calls on all devices when these are active. One example would be that all calls are routed to your assistant when your presence is set to “Away”.

Rainbow helps you bring everyone together

Employees, customers and suppliers are all part of your eco-system, so why not bring them together and invite them to join a Rainbow bubble (a group collaboration and/or web conference) and talk, chat, share documents or run audio/video conferences. This makes your interactions much more productive and interactive.
