SIS.0304 Error

Symptom

If the server does not receive any audio from the client for 20s, this error is reported.

Solution

1. Check the code to view whether there is too much idle time after an audio segment is sent.

2. Check whether an ending request is sent and the client is closed. If no data is sent and the connection is not disconnected after 20s, the error is reported. After using the service, disconnect the client from the server.
