Cool. But maybe we should change wording to “Kamailio logging system” and explain
that our logging system can log to multiple systems? 

More questions:

- Are we only logging to one log system - if I load the systemd logger - will we not log to syslog?

- Can we route different logging facilities to different logging systems?

Let’s say I want to use one set of xlog() statements to log to custom logger, one set to syslog,
is that possible?

Trying to figure out the architecture here.
