Well, I don't mean MESSAGE as a in-dialog request during an INVITE dialog, I 
just mean acting as a simple B2BUA hendling also MESSAGE, this is:

- I have a SIP proxy with user sip:alice at domain and sip:bob at domain.

- For any reason, I want a B2BUA in the path when alice sends a MESSAGE to 
bob.

- The proxy will route the MESSAGE to FS without changing the RURI, this is:
   ------------------
   MESSAGE sip:bob at domain SIP2.0
   From: sip:alice at domain;tag=111111
   To: sip:bob at domain
   Call-ID: AAAAA
   Contact: sip:alice at IP_alice
   -------------------
- I just want FS creating, as a B2BUA, a new leg like this:
   -------------------
   MESSAGE sip:bob at domain SIP2.0
   From: sip:alice at domain;tag=222222
   To: sip:bob at domain
   Call-ID: BBBBB
   Contact: sip:alice at IP_FS
   -------------------
and send it back to the proxy, this is, sending the MESSAGE to the Request 
URI. The proxy will receive the MESSAGE, lookup for bob location (it's also 
the registrar and location server) and route the MESSAGE to bob.

Is it possible? I didn't understand what you meant with "prefixes", why should 
I need prefixes in the example above?

Thanks a lot.
