Where does this happen?

You may encounter the warning in the powershell styled “PbxConfigTool” or during the web configuration guide.

When does this happen?

At first it is important to understand how the hostname is composed within 3CX and that also owned FQDNs are not exempted from this. Here the full take on FQDN management and allocation.

Commonly this happens in the below cases:

  1. The selected FQDN hostname is very common (e.g. 3CX) and another 3CX user has already reserved this name for their own use.
  2. You have installed the PBX already once before while using a different hostname during first time v15 installation.
  3. You have installed the PBX with a demo “PBX Edition” key and bought a new commercial license key (find out more on Evaluating 3CX and Converting a PBX Edition key to a Commercial Edition).
  4. You have installed the PBX with key A and now attempt to install key B with the same FQDN. (Find out more on Evaluating 3CX and Converting a PBX Edition key to a Commercial Edition).

How to solve it?

Case A

In this case you must pick another name. Extend the hostname with something unique, like your company name (e.g. 3cx -> 3cxcompany).  While using your own domain 3CX will use the first 2 dots to concatonate your PBX name (3cx.company.com -> 3cxcompany.3cx.net for the use of webmeeting).

Case B

You can still use the FQDN hostname you entered initially. However if you are unhappy with the initial pick or have forgotten it, you must release your key from your FQDN.*
If 3CX is still up and running it will immediately lose the external FQDN (when it is a 3CX hosted FQDN) and Web Meeting capabilities until it is reinstalled (all domains).

Case C & D

You can use a new FQDN for the new key. If the initial FQDN should be maintained and mapped to the new key, the “evaluation” key must be released from the FQDN in order to map it to the new key.* Also if a backup is in use to restore the 3CX configuration, this backup must not include the “license key” and/or “FQDN” of the previous installation! This will allow entering a new key and FQDN during restore time.

* Once the FQDN is not bound to any key, the hostname returns back into the public pool of available FQDNs. In this moment it can be registered by any other user. Therefore it is advisable to do the switching in a timely manner to avoid disappointment!
