How dos a user remove hum supply noises during an ongoing conference?
Solution
To solve this problem, disconnect external audio devices, such as a microphone. Check the ground status of the terminal and ensure that the terminal is connected to the ground and the connection resistance is not greater than 5 ohms. Then check the E1 cable by using the local loopback and point-to-point conference.
