I was thinking about changing the logging functions to filter on a specific
string. Something like debugInclude="pbx|sip"? Or exclude, or both?

I really felt it when I debugged my first app. I turned on debugging, since
I wanted to see all my app's stuff. But then I'm flooded with messages from
IAX, ZAP, PBX, etc.
