Re: [SR-Users] Kamailio breaks RFC's 'Contact Header'

Yes I did actually, I didn't remove it completely but gave an exception in the 
vein of -


event_route[topoh:msg-outgoing] {
  if($sndto(ip)=="10.1.1.10") {
    drop;
  }

Thanks Daniel and Henning!

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

Description

I'm running Kamailio 5.2.0, whenever I relay an invite via Kamailio, my 
original contact header is changed from the original:

sip:[email protected]:5060;transport=udp;gw=netvision

To

sip:YYY.YYY.YYY.YYY;line=sr-.n274i0TMfsHMcCAlVyAMV5IlgCXvV8n4edQlgIUlgKQ4Vk74gI1LmZ69NM79FZAR3JC.cDNLfHUj3Wnp3MP9nd*.

Even when I set it correctly on my route, using:

remove_hf("Contact");

append_hf("Contact: 
sip:[email protected]: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?
