Hello Steve,

Strictly speaking you can only Hangup (BYE) an answered and fully
established call. In SIP terms, a hangup that occurs before an answer
is a CANCEL, and I believe a CANCEL is always represented by a 503
code in chan_sip.

I see what you mean, but it is the called end (peer01) that rejects the
call with a 408 message, it is not the originator that is canceling the
call.
The call flow is this:
Caller->Asterisk->Peer01
and Asterisk receives a STATUS 408 message from Peer01 instead of an answer.
Asterisk then sends a STATUS 503 to the Caller, instead of sending a
STATUS 408. The question is how to "copy" the correct cause code from
the terminating end to the originating end.
I tried setting Hangup(1) to send a 404 to the called, a Hangup(17) to
send a 486 to the caller and pretty much any other value in the Hangup()
but Asterisk will keep on sending a 503.
I don't believe that my memory fails me, I'm pretty sure I could set a
desirable cause in the Hangup() command in previous versions...
