Additionally, for plain SIP traces, you can use the siptrace module.

Hi Noa,

Pretty much the only reasonable way to do it is to throw your own xlog()
statements into the default config, which contain the information you want.

The development community reasons that everyone is going to want
different logging points and different content in those logs, so it is
not necessarily appropriate to impose.

I would say throw a couple of xlog() statements in the config, maybe
like this:

xlog("L_INFO", "($ci) Entering NAT handler\n");

(logging the Call-ID lets you trace what happened to a single "call"
that shares Call-ID across all requests and replies)

Then, direct the output to a custom log file for easy viewing. Set the
syslog logging facility to, say, LOG_LOCAL0, and then redirect the
LOCAL0 facility in your syslog daemon to a separate file, e.g. in the
case of /etc/rsyslog.conf or Debian-style /etc/sysklogd.conf or classic
/etc/syslog.conf:

local0.* -/var/log/kamailio.log

Then restart the syslog daemon, restart Kamailio, and see if you like
what you get.

Cheers,

Is there a way to get a sensible amount of logging done from kamailio?

Being new to the VoIP space (but with plenty of experience with i.e. web
and email servers) I tried to get a running system by installing the
kamailio package and starting up, trying to get it to behave by looking
at log output. I use the blink SIP client in OSX, that has a SIP data
dump log view and from that I can deduce that the server returns
"SIP/2.0 483 Too Many Hops", however there is nothing helpful in the
server logs.

If I set debug=2 i get nothing useful, and if I set debug=3 I get insane
amounts of logging, thousands of lines per connection attempt. Finding
something meaningful in there seems like a herculean task.

/noa

ps. The actual problem with 483 Too Many Hops sounded a lot like 'Mail
loops back to myself' that you get on smtp servers when the relevant
virtual domain is not configured, so it seems I was able to handle that
problem by adding WITH_MULTIDOMAIN and configuring my domain with kamctl
domain add. Now I get "482 Loop Detected" instead, which seems like a
non-fatal condition. The logging question still stands though.
