There are two uris, which each FIFO request must include.

One of them is request-uri, which will show up in the resulting SIP message.

The other uri, "next hop" allows to override where the request is sent. Good 
if use of outbound proxy is dictated by a policy, or if next hop must be calculated 
for subsequent requests out of route set. (You may want to look at examples/ctd.sh 
how it is used for generation of subsequent REFER.) The uri is resolved to determine 
where to send the requests physically -- the request uri stays in first request's 
line but is not used to determine where the request will be sent.

If you don't wish to include the next-hop uri, leave a single-dot-line in
the FIFO request instead.

That's easy. Make your application using FIFO send to a file whose content you 
can read. Make it dump what it receives.
