well, there is no guarantee that after the lookup() you will have an IP 
in the domain part - it is up to the client what contact it uploaded 
(and you accepted :P )

you cannot know it prior to t_relay() - IP the RURI is an IP, then is 
fine, but if the RURI is a domain, the translation from domain to IP 
(via DNS) is done internally by t_relay(), so you do not have access to it.


not sure what you try to do, but maybe you should consider the blacklist 
capability of opensips:
