You can download VitalPBX directly from the downloads section in our website. You can then install it on a Virtual Machine or dedicated server. We also have some instructions on how to use a VPS installation script we have available if you want to install it on a VPS Service Provider.
Alternatively, we are also available on some VPS Provider marketplaces, such as Digital Ocean or SYSTM. Where you can create a machine that comes with VitalPBX installed already.
