This occurs because the rules with id=1 and id=3 do match the INVITE
so if the first fails (longest matching prefix) the other will be
executed. This is how LCR works.

Use load_gws() with a pseudo-variable as I recommend you in the other
mail so you won't rely on the From URI but on the call origin you have
previously analized in the script.
