I really do think you didn't make a call at all.
You didn't attach a wav file nor did you supply a tone generation at the commandline.
I definitely did a call, but you are correct to assume the worst :)
I even did a tcpdump capture, and using wireshark I see RTP traffic
going both ways. Even more - wireshark is able to show me the waveform
of the voice communication and play it out right from the pcap (how cool
is that?!).
Apparently pjsua does not need a tone instruction nor it require any
kind of sound sample - with the command line I used, it simply
"generates" silence and sends it as a G.711 stream.
If you look at the TX/RX stats I posted in my initial message, you will
see that it says "RX = total 336 pkts, TX = total 460 pkts".
But why it is unable to compute the RTT is a mystery to me. The PBX
server is 45ms away from me, so I'd expect this to show up in the stats...
Anyway, my three initial questions still hold :)
1. Is there a "proper" way to fetch call stats from pjsua? (other than
savagely grepping, seding and cutting its console output)
2. How should I instruct pjsua to quit when the call is over? Currently
I run it through the Linux "timeout" command so it gets killed after a
few seconds, but that's a really dirty way of doing business.
3. What may be the reason pjsua outputs "0.000" in its RTT stats output?
The stats are for media quality, but will show 0 when no RDP session was established !
Do you confirm that you do get some meaningful "RTT msec" values in
pjsua's output? Do you use vanilla pjsua code, as found in pjsip 2.9?
best,
Mateusz

Betreff: pjsua -- non-interactive mode for quality monitoring?
Hello list,
I am fiddling with the pjsua tool from pjsip 2.9, because I'd like to
use it to monitor the quality of my VoIP provider at home. I am able to
run a call all right, but pjsua does not exit once the call is
terminated - I have to press 'q' to quit the interactive shell.
Is there any trick I could use so pjsua performs the call, and exit once
the call ends? This is the command line I use now:
./pjsua-armv7l-unknown-linux-gnueabihf
--id='sip:mylogin@xxxxxxxxxxxxxxx' --realm='*' --username='mylogin'
--password='xxxxxx' --disable-stun --no-tcp --null-audio --no-vad
--max-calls=1 --duration=10 'sip:123@xxxxxxxxxxxxxxx' --no-color
Additionally, I'd need to get some stats from it. Currently I am
grepping the logs that pjsua outputs, to extract some data from this:
RX pt=0, last update:00h:00m:03.841s ago
total 336pkt 53.7KB (67.2KB +IP hdr) @avg=46.7Kbps/58.4Kbps
pkt loss=0 (0.0%), discrd=0 (0.0%), dup=0 (0.0%), reord=0 (0.0%)

RTT msec : 0.000 0.000 0.000 0.000 0.000
...but maybe there is some easier way? I noticed that 'RTT msec' always
shows 0.000, which is kind of strange. Any idea?
best,
Mateusz
