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.

  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.

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.

  If you can't start a presentation, check if a PC is connected to the VC400/VC120 codec and whether the PC is sending a signal. Also, check the call statistics to see if the system is already sharing content and ensure that dual-stream is configured 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.
