Hello Jonathan, Usually, you want to set the appropriate contact host in the initial INVITE and then the dialog stays βwithβ this contact. This can be done by just setting the xavp and is the way the topology module usually works.
Maybe you can elaborate why you want to change the contact in-dialog, or even in one transaction (onreply_route example below).

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?

You could just conditionally set the contact host to the different values, depending on your configuration logic.

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 Sent from Mail<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgo.microsoft.com%2Ffwlink%2F%3FLinkId%3D550986&data=04%7C01%7C%7C9e49a0c54f4b421b298c08d9b63407ce%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637741156850507690%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=TFVwLrGks3dvDMd1crtTyZyHcdrs1I3%2Bhu2suO%2BX9ZU%3D&reserved=0> for Windows
