Is the installation of 3CX affected by the settings of the configuration files prior to a new setup?

The correct answer is that configurations must be reset in the context of a new setup installation of 3CX. When a fresh installation is performed, the previous configuration files may contain specific settings that could interfere with the new setup. Resetting configurations ensures that any remnants of prior settings do not affect the newly installed system's operation, promoting a clean environment and helping to avoid potential conflicts or errors that could arise from old configurations.

This practice is especially crucial when setting up a system for the first time or when transitioning to a new version. It allows the administrator to start from a baseline configuration, making it easier to later configure the server as per the requirements of the new deployment. Ensuring that configurations are reset can prevent issues related to SIP trunking or other parameter mismatches that might have been set in earlier versions or different setups.
