<div>
<p class="MsoNormal" style="margin-left:35.4pt">I need Kamailio to be a sip proxy between two other SIP servers. All trunks are static IP only, no Auth. The specialty is that the Kamailio proxy needs to manipulate different fields in the SIP flow, depending
on which public IP is used. So, for example:<o:p></o:p></p>
