Hi sipp-users,
May I ask for second pair of eyes to see what I'm doing wrong here?
Here is what I'm trying to accomplish:
- My XML code checks the payload type specified by "[field6]" in the code
from a CSV file I'm injecting.
- When it's payload type 0, exec rtp_stream of a g711 wav file.
- When it's payload type 9, exec play_pcap of a g722 pcap file.
Here is the logic:
<nop>
<action>
<assignstr assign_to="1" value="[field6]" />
</action>
</nop>
<nop next="5" test="2">
<action>
<test assign_to="2" variable="1" compare="equal" value="0" />
</action>
</nop>
<nop next="4" test="3">
<action>
<test assign_to="3" variable="1" compare="equal" value="9" />
</action>
</nop>
<label id="5" />
<nop next="6">
<action>
<exec rtp_stream="/opt/sipp/g711-ulaw-msft.wav,-1,0" />
</action>
</nop>
<label id="4" />
<nop>
<action>
<exec play_pcap_audio="/opt/sipp/g722_sbstandup_short.pcap" />
</action>
</nop>
<label id="6" />
The issue I'm seeing is as follows:
- The G.711 rtp stream plays correctly.
- The G.722 pcap play does not play anything at all even though I see UDP
packets in my tcpdump output.
- With these conditional branching, I'm only limited to 540 calls on
single sipp process.
- Once I removed all the branching and just have play_pcap action on G.722
pcap file, that works fine and I can hear the media. Also, I'm able to get
700 concurrent users on a single sipp process.
What am I doing wrong here?
Thanks,
--Andy
