SIP 300 Multiple Choices vs 513 Message Too Large
SIP 300 (Multiple Choices) is a 3xx Redirection response, while 513 (Message Too Large) is a 5xx Server 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, 513 means that the server was unable to process the request since the entire SIP message (not just the body) exceeded the size limit.
