SIP 182 Queued vs 407 Proxy Authentication Required
SIP 182 (Queued) is a 1xx Provisional response, while 407 (Proxy Authentication Required) is a 4xx Client 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, 407 means that the client must first authenticate with the proxy. The proxy returns a Proxy-Authenticate header with a challenge.

이 코드를 보게 되는 경우
In call center or queuing scenarios where the callee is busy but the system holds the call in a queue.
해결 방법
Wait for the call to be dequeued. If queuing is not desired, configure the server to reject calls instead of queuing them.
설명
The client must first authenticate with the proxy. The proxy returns a Proxy-Authenticate header with a challenge.
이 코드를 보게 되는 경우
When a SIP proxy requires authentication before forwarding the request. Similar to 401 but for proxy servers.
