Hello,
I found the option '-aa' which helps me with the INFO issue. However, I have a
similar problem with arbitrary number of periodic re-INVITEs (they also arrive
during <pause>) where I would like a similar approach (preferably with a
customized response, instead of the built-in one). The '-aa' option covers only
INFO, UPDATE and NOTIFY...
I think that I could use the '-nd' option but I need to respond to the
re-INVITEs instead of ignoring them completely, otherwise the SUT closes the
call.
Thanks
Marek

Objet : [Sipp-users] SIP INFO (vfu) after re-INVITE
Hello,
I use latest "SIPp v2.0-PCAP, version 20070619, built Jun 20 2007, 13:31:07."
I have this scenario (based on UAC):
Messages Retrans Timeout Unexpected-Msg
INVITE ----------> 1 0 0
100 <---------- 0 0 0 0
180 <---------- 0 0 0 0
200 <---------- E-RTD1 1 0 0 0
ACK ----------> 1 0

[ NOP ]
INFO <---------- 1 0 0
200 ----------> 1 0

[ NOP ]
INVITE <---------- 1 0 0
200 ----------> 1 0
ACK <---------- 1 0 0
INFO <---------- 1 0 0
200 ----------> 1 0
Pause [ 1:00] 1 1
BYE ----------> 0 0 0
200 <---------- 0 0 0 0
After the INVITE which comes from the SUT I respond with 200 OK and then after
the ACK, INFO and 200 OK, I would like to pause (there is PCAP play which was
started after the first ACK, still going on during that period). However, after
reaching the <pause>, the call is aborted with
2007-06-20 13:42:31:922 1182339751.922596: Aborting call on unexpected
message for Call-ID '[EMAIL PROTECTED]': while expecting '0' response, received

<?xml version="1.0" encoding="utf-8"
?><media_control><vc_primitive><to_encoder><picture_fast_update></picture_fast_update></to_encoder></vc_primitive></media_control>
I tried to add an optional="true" into the <recv INFO> :
...
...
<recv request="INFO" optional="true">
<action>
<assign assign_to="1" value="1" />
</action>
</recv>
<send test="1">
<![CDATA[

[last_Call-ID:]
[last_CSeq:]
Content-Length: 0
]]>
</send>
<pause milliseconds="60000"/>
...
...
But then SIPP never sends the "200 OK" response - it stays at
Messages Retrans Timeout Unexpected-Msg
INVITE ----------> 1 0 0
100 <---------- 0 0 0 0
180 <---------- 0 0 0 0

receiving all the INFO messages, and never reaches the end of the scenario.
I would like either to automatically respond to every INFO with 200 OK, or to
simply ignore them all (at some point in the scenario). Is this possible?
Thanks
Marek
