Why is my Yealink Conference System remote control not working?
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 VC400 call the far site?
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.
What to do if the network keeps losing packets on Yealink VC400 Conference System?
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.
