<h3>Description</h3>
<p>I am currently implementing a dynamic forwarding server in Kamailio. As a logic consequence, I wanted to name it "forward.ng-voice.com" and I added it as an Alias:</p>
<p>alias=forward.ng-voice.com</p>
<h4>Reproduction</h4>
<p>Add any Alias with the "forward" in it's domain-name (e.g. "ims.forward.ng-voice.com" fails too).</p>
<h4>Log Messages</h4>
<pre><code> 0(20620) CRITICAL: <core> [core/cfg.y:3427]: yyerror_at(): parse error in config file forward.cfg, line 11, column 7-13: syntax error

</code></pre>
<h3>Possible Solutions</h3>
<p>Use a different Domain-Name like "fwd" or "forwarder".</p>
