I would prefer the log level being configurable; e.g. Jetty will output a large amount of unnecessary debug logs if the root logger is set to trace, so it would be convenient if the CallLogging feature could be configured to use a different log level, rather than having to set the root logger to trace and then configure the Jetty logger log level at info.
