Hi Rhys,
I would suggest '503' as is used for transaction errors (RFC3261 section
8.1.3.1) and sometimes for transport errors (16.9)
Regards,
Jeroen

Subject: [Sip-implementors] 100rel: 5xx response to INVITE forunacknowledged
reliable 101-199
Hi,
My apologies if this has been asked before; I couldn't find it in the
archives.
RFC 3262 Section 3 says "If a reliable provisional response is
retransmitted for 64*T1 seconds without reception of a coresponding PRACK,
the UAS SHOULD reject the original rquest with a 5xx response."
Which 5xx response is appropriate?
None of the 5xx error responses defined in RFC 3261 seem appropriate:
500 Server Internal Error
501 Not Implemented
502 Bad Gateway
503 Service Unavailable
504 Server Time-out
505 Version Not Supported
513 Message Too Large
504 seems like the best candidate, but the description seems vague in
Section 21.5.5.
The server did not receive a timely response from an external server
it accessed in attempting to process the request...
Thanks,
Rhys
