How to adjust the camera angle and focus on my Yealink VC120 Conference System?
- M
  Marc WilsonAug 30, 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.

Why doesn’t the display device display the correct time and date on my Yealink Conference System?
- C
  Charles HarrisSep 7, 2025
  If the display device does not display the time and date correctly, and you have configured the system to obtain the time and date from the NTP server automatically, ensure that the SNTP server and time zone are configured correctly in the system and that the connection between the system and the NTP server is working properly. If you have configured the system to obtain the time and date manually, ensure that you have configured the time and date correctly.

Why does my Yealink Conference System network keep losing packets?
- B
  Brandon MartinAug 29, 2025
  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.

Why can’t I adjust the remote camera during an active call using my Yealink VC120?
- J
  John GutierrezSep 9, 2025
  To troubleshoot adjusting the remote camera during an active call, first, use the remote control to control the local camera to ensure it functions normally. Then, verify that the far site has enabled the 'Far Control Near Camera' feature. Ensure that you are trying to control the remote camera by selecting 'More->Near/Far Camera' during an active call and selecting the remote video image. Finally, confirm that the far site supports the same call protocol as the local site.

Why doesn’t the status bar of the display device display the IP address on my Yealink VC120 Conference System?
- C
  Christina AlexanderSep 9, 2025
  If the status bar of the display device is not displaying the IP address, check whether the network is available, the LAN property is configured correctly, the system has enabled the hide IP address feature, and the system has configured the firewall and NAT correctly.

Why does the far-site display a black screen when the local site starts a presentation on my Yealink VC120 Conference System?
- J
  Joseph Cooper DDSSep 12, 2025
  If the far-site displays a black screen when the local site starts a presentation, this may be due to the difference between the Signaling Server address and the Media Server address. The actual address is different from the negotiated address, so starting a presentation in this situation will result in the failure of sending packets to the correct address. You can disable the network adaptive feature so that the system will send packets to the negotiated address rather than the actual address.

Why can't I hear audio during calls on my Yealink VC120 Conference System?
- M
  Matthew LongAug 27, 2025
  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.

- S
  Stephanie GarciaAug 27, 2025
  If the remote control isn’t working, first ensure the system is powered on. Then, check the battery polarity (+/-) and ensure the battery has sufficient power. Finally, make sure there are no special fluorescent or neon signs nearby that might interfere with the remote's signal.

Why won't my Yealink VC120 Conference System call the far site?
- E
  ericguzmanAug 26, 2025
  If the system fails to call the far site, check the network availability of both the near and far sites. Verify that the far site hasn't enabled the DND (Do Not Disturb) feature. Ensure accounts are correctly registered and the appropriate account is used for the call. Confirm the number you're calling is correct and that the far site isn't rejecting your call. Check if a firewall is blocking inbound traffic, if the far site has reached its call-in limit, if encryption settings are compatible, and if both sites support the same call protocol.

Why is the screen black on my Yealink Conference System?
- C
  Cody Garcia MDAug 26, 2025
  If the display device is black, verify that it's properly connected to the VC400/VC120 codec. Ensure the system isn't in sleep mode by pressing any key on the video conferencing phone or remote. Also, check if the display device itself is in sleep mode or turned off, and try switching the video input source to the correct one.
