Yes, I completely agree with that.

Why "480"? The RFC 3398 does this mapping for 480 code:

  480 Temporarily unavailable   -->   18 No user responding

Is it the best choice in the PSTN world?

Why do you say "this has nothing to do with 3398"? My question is with SIP 
code is the best reply to send to a PSTN gateway when the SIP user is not 
registered (but it does exists). Related to it there is a RFC 3398, so...


Thanks.
