if( msg_apply_changes())

                {

                        xlog("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");

                }

causes:

 0(3642) ERROR: <core> [cfg.y:3286]: yyparse(): cfg. parser: failed to find command msg_apply_changes (params 0)

 0(3642) : <core> [cfg.y:3426]: yyerror_at(): parse error in config file //etc/kamailio/kamailio.cfg, line 246, column 25: unknown command, missing loadmodule?

and again

0(3642) ERROR: <core> [cfg.y:3286]: yyparse(): cfg. parser: failed to find command msg_apply_changes (params 0)

 0(3642) : <core> [cfg.y:3426]: yyerror_at(): parse error in config file //etc/kamailio/kamailio.cfg, line 251, column 25: unknown command, missing loadmodule?

while if I do this:

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

 msg_apply_changes();

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

I get this:

Look inside syslog file to see the line where the errors are and description of the errors.

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,
