What can I do if my 3cx server goes offline

[Danny De Meyer]

There are planned works on a specific day on which the electricity will go down several times.
Phones will go unregistered, also the 3cx app for smartphone will not be able to work.
Is there any way to work around this so I can receive calls e.g. on my mobile phone when the 3cx server (on prem) goes down ?

Ask your sip trunk provider to forward calls to your mobile for that day?

 

[Danny De Meyer]

Alas, that is not an option
I would have to forward to different numbers in the morning and afternoon.

If I may suggest the following for your future consideration: consider hosting your on-premise PBX in the cloud.

This way, you will almost never have any down time. Cloud systems are not affected by internet outages or power outages at your building. Even if the building becomes entirely inaccessible, your users can always have access to their lines using their mobile over 4G.

Moving to the cloud is easy, but it does have some considerations. In case you want more details let us know and we can advise accordingly. If you want, you can have 3CX host it for you:

• We deploy your instance to cloud providers DigitalOcean or Vultr and automatically configure firewall rules.
• We manage the 3CX operating system, including security patches and version upgrades (i.e. from Debian 10 to Debian 11)
• We take nightly backups.
• We keep your 3CX on the latest non-beta update.
• We monitor your 3CX system 24/7

You can check pricing here if you are interested, it includes the license and hosting in one package: https://www.3cx.com/ordering/pricing/

A 3CX Partner in your area can take care of the license and the migration for you for minimal disruption.
