Hi Takeshi.
Thanks a lot for your help.
I tried the suggested but it doesn't work. I have a following action at
SIPp-UAS.xml:
<recv request="INVITE">
<action>
<ereg regexp=";tag=JuniperBSG[0-9]+" search_in="hdr"
header="From:" assign_to="2" check_it_inverse="true"/>
</action>
</recv>
According to Wireshark UAS receives INVITE request having following From
header:
From: SIPp-UAC
<sip:[email protected]>;tag=JuniperBSG97+1000002+11c0000+3065ca75
That is call supposed to be counted as failed at statistic screen. But I
see it as succeeded.
What am I doing wrong? Is check_it_inverse supported for SIPp-3.0?

Hello, Evgeny.
Everything is fine here. Hope all is good with you too.

You can use the undocumented check_it_inverse. This marks the call as
failed if the regexp matches. Ex:
<recv request="INVITE" crlf="true">
<action>
<ereg regexp="SIP123" search_in="hdr" header="From"
assign_to="match" check_it_inverse="true"/>
</action>
</recv>
<nop test="match" next="ERROR"/>
...Normal processing goes here...
<label id="ERROR" />
<send>
<![CDATA[
