That is conflicting with other changes to the contact header.

Try to use msg_apply_changes() before (and after) your subst operation for changing contact.

Do you have set_contact_alias() or fix_nated_contact() in your config file?

i am trying it but it doesn't change the string. Do I need to use msg_apply_changes() ??

I am trying that but it gives syntax error in the file.

log("L_INFO:", "INVITE::: [$ct]\n");

subst("/^Contact:(.*);transport=tls(.*)/Contact:\1;transport=udp\2/i");

if(msg_apply_changes())

{

     xlog("L_INFO:", "INVITE::: [$ct]\n");

}

Hi Rizwan,

You can try the following:

subst("/^Contact:(.*);transport=tls(.*)/Contact:\1;transport=udp\2/i");

On the other hand, there should not be any other contact header modification in your script; for example set_contact_alias().

Guys,

Is this a stupid question or this just cannot be done?

Any help will be highly appreciated.

Thanks,

I want to remove the transport=TLS from the contact header.

How can I do that inside Kamailio?  The flow is an under:

Client --------> Kamailio -------------> FS

           TLS                       UDP

Client <-------- Kamailio <------------- FS

           TLS                       UDP

FS gets a request on udp but it complains about TLS profile as the contact header has the transport=TLS. Since its receing traffic on UDP, if I only get rid of the value from the Contact Header, it would be great.

Thanks,
