3CX: self-host on VPS or take 3CX cloud?
Self-host saves licence, but you own SBC, backup and updates.
support/telefonie-voip/3cx-self-host-vs-cloudsteps: 4
Try this first
- Self-host: Debian VPS, ports 5060/5061 open, Let's Encrypt for TLS
- Cloud version: 3CX handles updates and backups, fixed price per simultaneous call
- Account for downtime: self-host means you handle 24/7
- STIR/SHAKEN and SBC features are in both
When to bring us in
No 24/7 team? Cloud, or let Vectel run a managed self-host.
