[Serusers] Check if user is registered without uri rewrite

Hello everyone, I am looking for an alternative for lookup(location) to check if a certain user/uri is registered with a location at ser, but without rewriting the to uri as I have to forward the call to another system, but need to know at first, if the user is registered. With lookup it won't work as it rewrites the to-uri with the contact-information of the client, which can be quite different from the original to-uri.
