<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">Hi all, <br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">I have an infrastructure with Kamailio (reg), Asterisks farm, and Kamailio (4.3) proxy which dispatches calls.
<br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"> Trunk-1 (Vlan_A)<br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">Kam(reg) <> Asterisk Farm (5) <> Kam(proxy) <> Trunk-2 (Vlan_B)<br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"> Trunk-3 (Vlan_C)</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">For each trunk, I have to use the IP of the VLAN interface in "contact header". That means when I need to send a call to Trunk-1 I have to set Vlan_A IP address on the contact header. I have
achieved that by rewriting Contact Header. <br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">###</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">remove_hf("Contact:");</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">append_hf("Contact: <sip:$fU@$var(recieved)>\r\n", "Call-ID"); #by using db<br>

<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">But this causes a problem, Kamailio does not forward the BYE message that comes from Trunk-X to Asterisk (In before, the BYE message had Asterisk IP in R-URI). However, when I use topoh module
it forward properly for one trunk. But I can not set multiple mask IP in topoh module.

<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">I'm using the dialog module and I thought it can handle all requests in one dialog to forward to the correct asterisk but it did not.

</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt"><br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">Is there any suggestion for this case?
<br>
</div>
<div style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt">And also how many sub-interfaces can Kamailio handle for a good performance? Or do you suggest multiple Kamailio instances instead of multiple sub-interfaces on one server?<br>
