We have multiple implementations of the 3CX Phone System 11 on x64, but for one specific instance in which we have implemented a windows service that makes a call to the Config Server, so that we can add an extension to a ring group for a time and then remove it. The service runs well for 2 weeks, then the 3CX Config server no longer becomes accessible. We get this error, “TCX.Configuration.Exceptions.PhoneSystemException: Config server is not connected”. The only fix for this is to restart the Config Server, which restarts all of the services. After restarting the Config Server, it is accessible again. Any thoughts?
