These cloud providers are supported by PBX express for creating 3CX instances under your own account. An account is required that is configured to allow creating machines via the API.
The guides below detail how to setup your account (in some cases providers have different types of accounts ) and what settings you need to configure in the account before you can run PBX express
It should be noted that at times the cloud providers are not able to create instances via the API. If you receive an error check that your account is correctly configured and that the cloud provider is able to create instances for you at the time of running PBX Express.
