This is just information. Actually each logging information carries a
verbosity level (from 5/tracing to 1/fatal error), but this
information is not printed to screen/file. On Windows you'll get
different colors for each verbosity so it's easier to distinguish
errors from infos.

Hmm, not sure. Can't find any good reason why not, but I kinda of like
it this way (or maybe it's because I'm so used to it).

It's discussed here: http://trac.pjsip.org/repos/wiki/FAQ#ringtone

Sure. I've put this feature on some command (like "cc", "cd") but
haven't applied it to any other commands.

Not sure about that. For me I prefer pjsua to be concise. Anything
more intelligent should be done by a proper user interface.

We already have that. Messages important to users are logged at
verbosity 3 or lower. Verbosity higher than 3 (e.g. 4 and 5) are just
more details.

I have thought about "expect", but I think probably it's not a good
idea considering that the log messages now are not too consistently
formatted (e.g. "Call 0: disconnected" vs "Some message for call 0").

My general feeling is I think you'd probably be happier with creating
another pjsua as your scripting core. And that's what Python is for.
