I am getting this error sending calls from my Kamailio box on 192.168.0.250.

2011-01-03 14:22:49.930896 [WARNING] sofia.c:6369 IP 192.168.0.250 Rejected by acl "domains"

Here is the contents of my ACL:

<configuration name="acl.conf" description="Network Lists">
  <network-lists>

    <list name="lan" default="allow">
      <node type="allow" cidr="192.168.0.250/32"/>
    </list>

    <list name="domains" default="deny">
        <node type="allow" domain="$${domain}"/>
        <node type="allow" domain="192.168.0.250/32"/>
    </list>

  </network-lists>
</configuration>

I do not understand why calls from this machine are being rejected. Kamailio and Freeswitch are on the same machine sharing the same IP. Any ideas what I am missing?
