<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
domain table must contains the hostnames associated with the Kamailio server. Eventually you can add local ip addresses, but they are redundant if you just want to compare with 'myself'. You must not add in the domain table the ip addresses of client devices
(phones).<br>
<br>
By adding an ip address to domain table you tell kamailio to consider the uri that has that IP as for itself. So, practically instead of forwarding to IP 10.0.0.40, you tell to kamailio to handle locally the requests with uri including 10.0.0.40.<br>
<br>
You should just remove 10.0.0.40 from domain table, I see no reason to have it there, given it is one used by a client device.<br>
<br>
Cheers,<br>
