Hello,
Quoting from the bug report, where Daniel already replied:
It looks like you are using topoh module, which has the purpose of changing the headers that contain ip addresses. Remove it from your config.
Have you tried already to deactivate this module in your cfg?
Cheers,
Henning

Subject: [SR-Users] Kamailio breaks RFC's 'Contact Header'
Description
I'm running Kamailio 5.2.0, whenever I relay an invite via Kamailio, my original contact header is changed from the original:
To
Even when I set it correctly on my route, using:
remove_hf("Contact");
append_hf("Contact: sip:$tU@YYY.YYY.YYY.YYY:5060;transport=udp;gw=netvision\r\n", "Contact");
It still ends up being modified.
What can I do to keep the contact header as it is?
