so the subscriber only see’s public IP address in the SIP contact host and responds to it, and the carrier only see’s the private IP address in the contact host so they respond to the appropriate IP address, so its topology hiding IP addresses across interfaces.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">Hi All,<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">I was wondering if anyone can help, and advise me if I am missing something when using topos in an environment where I have more than one interface for kamailio.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">Essentially I would like to set the contact_host to 2 different values depending on the flow of the SIP requests, as we have a private LAN interconnect for example 10.10.10.10, and a public
interconnect using 2.2.2.2 (for example).<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">I notice there is xavu for A-side contact and B-side contact, but what about just the contact host?<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">As I have set for example;<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">And this works fine but obviously sets the contact_host to 8.8.8.8 across both interfaces, I ideally want it to change between 10.10.10.10 and 2.2.2.2.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:141.6pt"><span lang="EN-GB">How can I set more than one contact_host $xavu that topos can use? As my understanding is you can only set $xavu once, so is there another way to manipulate the contact_host on requests coming
in and out on different interfaces? I assume I am missing something? :)<o:p></o:p></span></p>
