manual.

Video/Display
Video conference call is established but no video or voice.
- If you are connecting to AVer EVC with firewall, make sure you have done the port forwarding
correctly. For non H.323 ALG firewall, please set the NAT configuration and the WAN IP
address on AVer EVC system is entered.
- We suggest having a fixed public IP address for AVer EVC system. With Dynamic public IP
address, it will change after a certain period which depends on your local ISP.
- There is a routing issue if you installed two AVer EVC systems sharing one public IP address.
Unable to connect to other video conferencing systems.

- Ensure the power status of the device from the other sited is on.
- Verify if the firewall blocks the inbound traffics from the other site.

- Make sure your system and display are well-connected and then reboot your system. (Your
display should be switched on before you reboot your system.)

shown).
Why can’t I see the UI configuration screen after connecting the VGA cable and powering on AVer
