Use Cases and Deployment Scope
We looked at FreePBX to replace our aging Cisco Voice Gateway. We installed it on VMware originally and eventually migrated it to Hyper-V without much issue. We were able to partner it with IBM's Watson for voice mail transcripts and create options for softphones on mobile and desktop. We also integrated it with our speaker system to create timed and emergency announcements throughout the campus.
