<h3>Description</h3>

<p>Kamailio start failed as carrierrouter</p>
<h3>Troubleshooting</h3>
<p>Main error<br>
<code>[parser_carrierroute.c:271]: parse_options(): Duplicate option definition max_targets</code></p>
<h4>Reproduction</h4>
<p>Define module</p>
<pre><code>modparam("carrierroute", "config_source", "file")
modparam("carrierroute", "match_mode", 128)
modparam("carrierroute", "config_file", "/etc/kamailio/carrierroute.conf")

</code></pre>
<p>Create carrierroute.conf like in module documentation</p>
<pre><code>domain first {
    prefix + {
        max_targets = 2 
            target 192.168.1.1 {
                prob = 0.500000
                hash_index = 1
                status = 1
                comment = "First Master"
