Hosted with 3CX - Explained

3CX hosting frees your time and resources as we manage your 3CX system for you.

• We deploy your instance to the cloud provider and automatically configure firewall rules.
• We manage 3CX and the operating system, including security patches and version upgrades.
• We keep your 3CX on the latest non-beta update.
• We monitor your 3CX system 24/7.

3CX’s hosted service is distributed over reputable providers, over dozens of data centers worldwide. Average SLA time is 99.99%. Please note that during system updates, i.e. upgrading to a newer version, your system may experience limited downtime. We will, however, inform you before taking any action.

Switching to Hosted

New customers can select between 3CX SMB FREE - Small Business for up to 10 users and 3CX Hosted for a dedicated instance and above 10 users whilst initiating the 3CX trial.

Existing on-premise and private cloud installations can switch to hosted directly from the customer portal. Simply click on “Switch to Hosted” under “My Systems” and follow the steps. Read the manual here for more information on how to migrate. You can purchase a migration support ticket at any time in case of any issues.

3CX's hosting service is available in over 50 countries.

Requirements / Limitations

• IP phones must be configured behind a 3CX SBC or router phone. Consider using 3CX Apps instead for seamless remote working!
• It is recommended to use a supported SIP trunk provider.
• You will not get SSH access to the machine – all operating system management is done by 3CX.
• We do not support IP-Phones which are connected via STUN to a hosted instance. All IP-Phones must be connected using the 3CX SBC or a router phone.
• We do not take backups of any part of your 3CX system. This includes configuration data as well as call related data such as call history, voicemails, and recordings. Backups are not retained for disaster recovery purposes. While we may create occasional internal backups for operational tasks (such as system migrations), these are not guaranteed, not retained, and should not be relied upon.
• As the system administrator, you are responsible for configuring and maintaining your own backup strategy. We strongly recommend setting up remote storage for your 3CX instance to securely store your backups and call data.
