Configuring Polycom Video Conference System - HDX 8000

My company is using Polycom solution to provide video conference for all branches. Recently there is a issue which one way video and audio from my site. What I found trick part is the firewall settings on Polycom.

I would like to go through main configurations on our Device first:

1. On system settings page, set up name and other basic properties.
2. Network Configuration:

Do not forget to put DNS servers in it, else your time server test will be failure. Default time server is ntp.polycom.com

3. Other additional settings, such as snmp, multiple camera, multiple screen support, multipoint support. Some of them may need license to support it.

4. Since we are using Internal IP address, this device definitely is behind firewall or other security devices. During testing, we found we could not get video and audio but other site can see and hear us. After searched some documents and played a little bit, we found trick part is NAT configuration on HDX 8000.

5. Test sites from Polycom Support Page

6. Enable Remote Monitoring

By default, we could not see camera snapshot from remote website. There is no option you can enable it from GUI. 

Another trick is to do it from Physical Device by remote controller at meeting room. 

after enabled Video over the web, you will see near end video or you will see both near and far end in a call. Also you can control pan left, right, close, further etc.
