Meeting solutions are real-time collaboration applications and associated endpoints that support interactions over a network between participants for team work, presentations, training and webinars. Some vendors segment their product lines to target and scale to one or several of those use cases, while others offer broad solutions that work for many purposes. Enterprise offerings in this market perform equally well for workers in meeting spaces, at their desks or when mobile, with integrated voice, video, messaging and content sharing. Organizations with complex needs typically have meeting solutions for internal use — for collaboration, learning and internal communication — that are separate from those for external use in sales or marketing. Such complex needs can result in running meeting solutions from more than one vendor. Complete meeting solutions enable richness of information and interaction by combining messaging, content and screen sharing, video and audio.
