<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
yes, the return codes are interpreted in a special way, see:<br>
<br>
- <a href="http://www.kamailio.org/wiki/cookbooks/devel/core#return">http://www.kamailio.org/wiki/cookbooks/devel/core#return</a><br>
<br>
Same applies for the functions exported by the modules.<br>

<p class="MsoNormal">Just a sanity check, really. Does Kamailio consider negative response codes to be false? For example, should the following log execute?<o:p></o:p></p>

<p class="MsoNormal">The reason for asking here is that I’m implementing flood protection using pike, based off the kamailio.cfg that ships with v4.3. The logic is thus:<o:p></o:p></p>

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">However pike_check_req only returns -1 or -2 in the case of failure, never 0. The blocking code is, thus, never executed. Changing to explicitly check for != 1 works correctly.<o:p></o:p></p>
