Cisco Collaboration Flex Plan - Cloud Calling and Meetings includes Cisco's cloud Calling, cloud Meetings, and team collaboration capabilities in a single Named User subscription. It is ideal for customers who are getting started with Calling, Meetings, and team collaboration, and is optimized for organizations with fewer than 250 subscribers. It allows you to choose entitlements for cloud Calling and Meetings and team collaboration for specific, named knowledge workers. And it gives you flexibility as adoption increases. Following your initial deployment, you can add Calling and team collaboration entitlements for additional knowledge workers to your initial Calling and Meetings purchase. You can then add meetings entitlements for those additional knowledge workers when they are required.
