You’ll also have video conferencing for all users. PBXinaflash is easy to install - IP Phones, Trunks and gateways will be automatically configured. But What really separates PBX in a Flash 5 from the competition is its painless upgradeability and management! The underlying Debian operating system can be automatically updated, as well as 3CX V15.5. You can install PBXinaflash 5.5 in a virtual machine, directly onto hardware, or run it in the cloud using for example Google Cloud or OVH.
