SIP 300 Multiple Choices vs 407 Proxy Authentication Required
SIP 300 (Multiple Choices) is a 3xx Redirection response, while 407 (Proxy Authentication Required) is a 4xx Client Failure response. 300 indicates that the address in the request resolved to several choices, each with its own location. The user or UA can select a preferred communication endpoint. In contrast, 407 means that the client must first authenticate with the proxy. The proxy returns a Proxy-Authenticate header with a challenge.
