SIP 182 Queued vs 603 Decline
SIP 182 (Queued) is a 1xx Provisional response, while 603 (Decline) is a 6xx Global Failure response. 182 indicates that the called party is temporarily unavailable but the server has decided to queue the call rather than reject it. The call will be attempted when the callee becomes available. In contrast, 603 means that the callee's machine was contacted successfully but the user explicitly does not wish to or cannot participate. Unlike 600, this may be because the callee doesn't want to communicate, not necessarily
