Setting the Codec type to G.711 can help eliminate which type of error?

Setting the Codec type to G.711 can help eliminate '488 Not Acceptable Here' errors because this type of error typically occurs when the media capabilities being offered by one party are not acceptable to the other party during a SIP (Session Initiation Protocol) call setup.

G.711 is a well-established and widely supported audio codec that maintains high voice quality and low latency. When both communicating parties support G.711, it increases the chances that the media negotiation for the call will succeed, thereby avoiding compatibility issues that could lead to a '488 Not Acceptable Here' response. This error could arise if one party offers a codec that the other does not support, leading to a failure in establishing the audio stream for the call.

In contrast, the other errors listed do not relate directly to codec compatibility. '500 Internal Server Error' indicates a generic failure at the server side, '404 Not Found' signifies that the requested resource could not be found (e.g., a user or service), and '401 Unauthorized' means that authentication is required, which does not pertain to codec negotiation at all.
