Hi,
i use version 2.9 only with the patch i commited (FFMPEG) as well as one from Andreas.
My check_call_loop connects a wav file (with text2speech) to the conference bridge and it will start to play when CONFIRM (200) has been sent. So, my wav file is 14s long. RTT is 20ms via SIP->GSM->SIP.
So basically, the client is also a server when using pjsua callbacks.
For the mainloop i use the superb EV Library (http://software.schmorp.de/pkg/EV.html).
pjsua uses and endless for loop, so the program won't be closed.
My guess is, that when you send silence, there are only protocol level packets but no stream, therefore the stats show "0".
My 14s call loop output: (keep in mind, that it calls a number which will be rerouted to SIP using another subscriber and calls back the app. So i have call 0 TX and call1 RX):
Here one call (obfuscated IP addresses and contacts etc)

Hello Franz,

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

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
