Really? Interesting, I had no idea. I thought the rtpproxy control protocol was binary and
did not lend itself easily to interaction in this manner. Thanks for the tip.

You can't get it from rtpproxy. You'd really
have to use something like the
dialog or htable modules to keep call state and get that from Kamailio.
On the contrary it's possible (using raw UDP reads/writes):
work ~: echo "h1u203u03 I\n" | nc -w 1 -u 127.0.0.1 22222
sessions created: 0
active sessions: 0
active streams: 0
work ~:
Where
* h1u203u03 is randomly chosen token,
* 127.0.0.1 is the rtpproxy's control IP,
* 22222 is the rtpproxy's control port,
* "-u" means that we're using UDP
* -w 1 is the timeout in seconds to wait before closing nc.
I can't imagine that someone will use nc in performance testing but I
think it looks like a good start.

Ok, I'm tagging dialogs with dlg_manage(), but even if the call ends,
it still keeps info about this dialog in list "kamctl fifo dlg_list".
Should I somehow close the dialog when the BYE transaction is ended ?
Peter: Thanks for the tip! Really interesting. But I do not
understand, why also this list contains the calls that were ended by
sipp... Should I search for some mistake in my kamaillio config ?

Perhaps you don't close them with unforce_rtp_proxy:
if(method=="BYE" || method=="CANCEL"){
unforce_rtp_proxy();
}

I'm using rtpproxy_manage, so I assume unforce_rtp is not needed.

Yep, this command protocol allows us to do tricks like this which is
quite helpful for debugging. Unfortunately this particular command (
'I' and its counterpart 'Ib' ) seems to be broken - it doesn't
prepend

Just FYI - I collected some examples of control commands here (just
grep for ser_proto:decode):
* https://raw.github.com/lemenkov/erlrtpproxy/master/test/ser_proto_test.erl
and here (which could be even more interesting since it contains an
example of a real session - create session, lookup, destroy, get
stats, etc):

Thanks for the tip.
Anytime :)
