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

while if I do this:
xlog("L_INFO:", "INVITE::: [$ct]\n");
msg_apply_changes();
xlog("L_INFO:", "INVITE::: [$ct]\n");
I get this:
