Re: [Sipp-users] check_it

[Jeff W. <JW...@az...>]

Charles,

Thanks for responding.  That scenario does look like it will work, but I was certainly unaware of the existence of the "strcmp" and "nop" actions, as well as the "condexec" action modifier.  I don't see these items in the documentation anywhere.  I guess I could grep through the codebase and try to figure out all the sundry options available to me and how they work, but that was a bit more than I was originally hoping for.

In any case, when I try this:

  <recv response="200" optional="true" next="1">
      <action>
          <ereg regexp=".*" search_in="hdr" header="Contact:" assign_to="contact"/>
          <strcmp assign_to="compareval" variable="contact" value="" />
          <test assign_to="empty" variable="compareval" value="0" test="equal" />
    </action> 
  </recv>

  <nop condexec="empty">
      <action>
          <error message="Server header is present.">
          </action>
  </nop>

I get this result:


"strcmp 'assign_to' parameter, "compareval" is not a valid integer!"

BTW, my sipp version is: SIPp v2.0-TLS, version 20071128, built Jan  7 2008, 16:31:36

Any ideas?

My best suggestion would be to assign the captured value to a variable, 
something like (not 100% sure on syntax, but this should sketch the plan 
for you); then strcmp it to an empty string (returns 0 if equal), and test 
on the strcmp return.

<recv>
<ereg assign_to="server" search_in="header" header="Server:" regexp=".*" 
/>
<strcmp assign_to="compareval" variable="server" value="" />
<test assign_to="empty" variable="compareval" value="0" test="equal" />
</recv>

<nop condexec="empty">
        <action>
                <error message="Server header is present.">
        </action>
</nop>

This is the exact same thing I need to do (see my post from a couple of 
days ago).  Please let me know if you find out a way to do it.

Hi ,

I would like to write a scenario as below.

Search the SIP message for the presence of a header, Server (for
example). If it is present then I would like to fail the call. I am
not able to achieve it using check_it.

Cheers
David
