Unable to establish real-time connection. Please ask the administrator of your main server to configure a TURN server so that calls can work reliably.

### Steps to reproduce

I have set up a synbase and coturn service in a private cloud. When two different devices are making voice calls, they can connect normally for the first two minutes, but after two minutes, they will disconnect, prompting "Unable to establish real-time connection.
Please ask the administrator of your main server to configure a TURN server so that calls can work reliably"

### Outcome

I hope voice calls can be kept on until they are actively closed.
