The maker also describes AI features for call and voicemail transcription, notes, summaries, and sentiment analysis. PBX deployments can run on customer infrastructure, Azure, AWS, or GCE, in a cloud, data center, or on premises using Docker. Microsoft 365 integration supports user provisioning, single sign-on in web and native apps, and directory and contact syncing. The PBX Free Edition costs nothing and supports 3 extensions and 2 simultaneous calls. Paid PBX licenses require a quote and may be perpetual or annual.
