With sip trace you still get them in a DB, because it first stores to DB 
and then sends to another address. However, what you want to achieve is 
something good, so for the future I will have in mind the option just to 
replicate to another address and skip writing to db.

If you want to duplicate the messages that come to kamailio, you can use 
the send() function in route and onreply_route block.

If you want the siptrace module to do it, you have to hack it a bit. 
Practically is to introduce a new parameter, e.g., skip_db_storage, and 
put the code that writes in db inside a if not skip_db_storage.

Cheers,
Daniel
