Kristian, Unfortunately, 603 Declined is frequently misused this way by service providers and SIP stacks. It seems to be a catch-all epithet for some sort of miscellaneous call completion failure that cannot be categorised any other way, much like 503 Service Unavailable.
I agree 100% with this statement, and have taken this position for a long time: On 01/28/2010 04:17 PM, Kristian Kielhofner wrote: > "returned only if the client (Asterisk) knows that no other end point > will answer the request" > > That's a little presumptive of the Asterisk system, don't you think? > ;) While I don't have any better alternative responses I'm just > bothered by the "global" nature of 6xx failures in the first place. It's also problematic because a 3261-compliant SIP proxy or UAC is not going to attempt to reach the destination by alternate means (serial forking in the case of the proxy, or a new call leg in the case of the UA) because of this precise implication of 6xx-class final replies. -- Alex -- Alex Balashov - Principal Evariste Systems LLC Tel : +1 678-954-0670 Direct : +1 678-954-0671 Web : http://www.evaristesys.com/ -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
