<p class="MsoNormal">Hello Henning,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Yes your comments make perfect sense.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Essentially I want to change the contact in-dialog as essentially the initial INVITE comes in on a private interface from the carrier, and then goes out on a public interface to the subscriber, 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.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have done a similar thing with hash tables before and using record_route_preset but was hoping I could do a similar thing with topos and leave it to manage the dialog.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does that make sense?</p>

<p class="MsoNormal" style="margin-left:35.4pt">Yes I conditionally want to set it, I have tried this but not sure it has worked to this point hence why I am wondering if I am missing something.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:35.4pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:35.4pt">Say for example I have request coming in from carrier on 10.10.10.10 interface and want to route to subscriber who is registered, so flow is simple its just;<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:35.4pt">On branch route out I have set the contact_host to a particular IP address, however on_reply I want to change it again to another IP address, can I do that using the $xavu ?

<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">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></p>
<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">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></p>
<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">I notice there is xavu for A-side contact and B-side contact, but what about just the contact host?<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">As I have set for example;<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">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></p>
<p class="MsoNormal" style="margin-left:70.8pt"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:70.8pt">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></p>
