HI Henning,

Yes sorry late night 😊 and thank you for reply.

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.

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;

Carrier--->kamailio-->subscriber

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 ?

So branch sees contact host as one IP address, and onreply I change it to 
another IP.

As currently if I set the Host it stays the same on both sides.

Does that make sense?

Jon

Hello,

There might be a spelling error below, you probably mean:

“$xavu(_tps_=>contact_host) = "2.2.2.2";
And this works fine but obviously sets the contact_host to 2.2.2.2 across both 
interfaces, I ideally want it to change between 10.10.10.10 and 2.2.2.2.”

Not sure if I understand your question correctly. You could just conditionally 
set the contact host to the different values, depending on your configuration 
logic.

Cheers,

Henning

Subject: [SR-Users] topos xavu_field_contact_host kamailio 5.5

Hi All,

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.

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).

I notice there is xavu for A-side contact and B-side contact, but what about 
just the contact host?

As I have set for example;

modparam("topos", "xavu_cfg", "_tps_")
modparam("topos", "xavu_field_contact_host", "contact_host")
...
    $xavu(_tps_=>contact_host) = "2.2.2.2";

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.

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? :)

Thanks in advance

Jon
