SIP 300 Multiple Choices vs 416 Unsupported URI Scheme
SIP 300 (Multiple Choices) is a 3xx Redirection response, while 416 (Unsupported URI Scheme) 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, 416 means that the server cannot process the request because the URI scheme in the Request-URI is unknown to the server.
