<p><code>KSR.rr.is_direction(...)</code> returns <code>1</code> if the direction is matching the parameter and <code>-1</code> if not. It does not return <code>true</code> or <code>false</code>, therefore be sure you do the appropriate comparison, it is different that kamailio.cfg language, where a negative return value is evaluated as false and positive is evaluate to true. In Lua, you have to do <code><0</code> or <code>>0</code>.</p>
<p>Then, there is no function exported by kamailio <code>headers.get("$rdir(name)")</code>.</p>
<p>So overall, it looks like misunderstanding/misuse, rather than a bug in the code. You can discuss more or sr-users if you have further questions about using KEMI and Lua. If it proves to be a bug somewhere, then this can be reopen.</p>
