After taking a backup of a 3CX installation where the SIP Port was changed to 6060, will a new installation of 3CX still use port 6060 when restoring that backup?

When restoring a backup of a 3CX installation, the SIP port settings from the original installation are not automatically applied to the new installation unless specifically configured to do so. The default SIP port for 3CX is typically 5060, and upon a fresh installation, it will use this default setting unless changed during the installation process.

After a backup is taken, the restored system will adhere to the configuration chosen during the installation. Since SIP port settings are part of the installation configuration rather than the backup, the new installation will revert to the default settings unless the administrator configures it to utilize the specific port that was previously set, in this case, port 6060. This means that simply restoring a backup does not carry over custom port settings, and the user must decide to apply any changes to SIP port configurations after installation.
