Why can't I hear the other site clearly on my Yealink VC400 Conference System during a call?
- L
  Linda BrennanSep 4, 2025
  If you can’t hear the other site clearly, ensure that their speaker volume is not set too low. Muffled audio may be due to highly reverberant rooms. Adjust the priority order for your audio codec, especially if a low-bandwidth codec is first. For best results, ensure the caller uses a Yealink video conferencing system. Dust and debris may also affect audio quality.

Why can't I adjust the remote camera during a call on my Yealink VC400 Conference System?

  If you can't adjust the remote camera during a call, use the remote control to control the local camera to ensure it functions normally. Confirm that the far site has enabled the Far Control Near Camera feature and that you are attempting to control the remote camera. Also, ensure the far site supports the same call protocol as the near site.

  If the network keeps losing packets, check whether the network is available and if the LED indicator on the left of the Internet port illuminates green. Try using a low-speed connection to check whether packets are lost, as deficient bandwidth can cause packet loss. Also, check the configuration of the network speed and duplex mode on the system, switch, and router.

  Vincent BruceSep 1, 2025
  To adjust the camera angle and focus, ensure you are doing so when the system is idle or during a call. Check the remote control batteries are working, installed correctly, and aim it at the sensor without obstructions. Confirm the camera's LED flashes green when using the remote. Make sure you are controlling the local camera. If issues persist, reboot the system or consider the remote may be broken.

  If the network keeps losing packets, check if the network is available and the LED indicator on the left of the Internet port is green. Try using a low-speed connection to see if packets are still lost. Also, check the configuration of the network speed and duplex mode on the system, switch, and router.

  If you can't view the local video image, check that the near site camera is correctly connected to the VC400/VC120 codec and that the camera is powered on with the LED indicator illuminated green. Ensure the camera is selected as the current video input source and that the screen layout isn't set to display the remote video image in full size.

Why is the voice quality poor on my Yealink VC400?
- V
  Vanessa LoweAug 28, 2025
  Poor voice quality can be due to several factors. Ensure users are not too far from or too close to the microphone, and avoid frequent movement of the audio pickup device. Intermittent voice may be caused by voice packet loss or jitter. Noise from devices like computers or fans can also affect clarity. Try replacing old cables to improve connectivity.

  If you can't hear audio during a call, first ensure that the local audio output device is correctly connected. Next, use the audio diagnose feature to check if the audio device is working normally. Also, verify that the ringer volume isn't set to the minimum and that the far site isn't muted.
