[SIPForum-discussion] SIP Response 520

[mjhorse]

Hi
 I don't look into this draft, but what I'm concerned with is how to determine whether a reason code is used or not? As I think 520/503/507 is the same if we just want define a new failling situation, how can I tell if I want to define some for my own design? Or I use a code arbitrarily only take into account its category(1xx-6xx, I mean)?

Hi,
 
 
 
I think the use of this response code was abandoned in the latest draft (draft-hilt-sipping-overload-04)…
 
Overload now seems to use 503 or 507, and the oc parameter, to indicate congestion.

A SIP server that rejects a request because of overload MUST reject this request with a 520 response code. 520 is a new SIP response code defined. This response code is used for requests that are rejected because the SIP server has received an indication that its downstream neighbor is overloaded or because the SIP server itself is under overload.
