From RFC 3920, 4.7.1:

"... if the initiating entity provides an unknown host in the 'to' attribute 
(or provides no 'to' attribute at all), the server SHOULD provide the 
server's authoritative hostname in the 'from' attribute of the stream header 
sent before termination."

This could happen if there is an error while the stream is being set up, like 
if you telnet to port 5269 and type jibberish.
