I can send a pcap file from the UAS by simply adding the "exec
play_pcap_audio" command and removing the optional="true" statement from
the default UAS xml file (http://sipp.sourceforge.net/doc/uas.xml.html),
ie:
<recv request="ACK"
rtd="true"
crlf="true">
</recv>
<nop>
<action>
<exec play_pcap_audio="pcap/g711a.pcap"/>
</action>
</nop>
<pause milliseconds="8000"/>
For the UAC, I am using the one from
http://sipp.sourceforge.net/doc/uac_pcap.xml.html.
The commands I am using are:
- From UAC: sipp -sf uac_with_G711a_media.xml 192.168.0.2 -users 1 -mi
192.168.0.3 -i 192.168.0.3
- From UAS: sipp -sf uas_with_G711a_media.xml -mi 192.168.0.3 -i
192.168.0.3
-> However from the network trace I noticed that the UAS duplicates each
packet it sends. It results in the weird call flow (see below) and a RTP
stream with twice as many packets as it should have (pcap file from UAS to
UAC contains 724 packets instead of 362).
I would be grateful if someone could send me a copy of their UAS and UAC
xml file if they have managed to send media from the UAS successfully.
Shridhar, I also used the xml files you sent me but I have the same
problem (as the scenarios I am using are pretty much the same). Have you
noticed the issue I described above? If I play back the G711 stream coming
from UAS in Wireshark, it is like playing the stream in slow motion as it
is actuall 14 seconds long instead of 7 seconds as shown in the call flow.
CALL FLOW BETWEEN UAC AND UAS:

[Sipp-users] UAS able to send media?

Hi all,
Is it possible to have the UAS send media? If so, I am unable to do
this with my attached scenario. I am able send media from the UAC.
Cheers,
Steve

[Sipp-users] UAS able to send media?

Looks like UAS is able to send media. My problem was the statement just
previous to the <nop> was marked as optional.
Shouldn't SIPp generate a warning when something like what I did is
done?
SIPp should ensure that the statement following an optional statement is
not a <send> or <nop> etc. If the statement following the optional
statement is a send or nop, a warning should be generated. Is this too
simple minded? What do you guys think?
Cheers,
S

Steve,
There should be a check like the one you described.
There was code for checkng sends and pauses but not nops. I factored out
the code (and made it a bit simpler). It is revision 527. It seems to
work, but we'll see if there is any fall out from previously good
scenarios flagging an error (I don't think there should be, but we'll
see).
