Use Cases and Deployment Scope
I support multiple customers, most of whom are long-time on-prem users, who are migrating some or all of their calling to the cloud. I have one who is exclusively using workspaces to provide multi-vendor-based conferencing services to a nationwide clientele. I have another customer who is migrating remote sites to Cisco Call in MS Teams for flexibility. And I have a third customer who uses Webex exclusively.
