Polycom HDX 8000 and Cisco Router 857: No Video and No Audio

Hello,
I have connected Polycom HDX 8000 to the Cisco Router 857 with Static Public IP on Polycom.
After making a call I am not able to see video from the far site but can listen the audio and far site cannot hear my audio and cannot see video.

I am not able to understand what's the issue since it is directly connected and there is no NATing or anything else.

Please can someone help me to resolve this issue.

Thanks

Please can you tell me where I can find the option in HDX 800 to lower the resolution.

Thanks

Make sure the HDX 8000 and monitor(s) are powered on
• Press the Call button on the remote to place a call
• A dialing window will open on your monitor along the top of the home screen
• Use the numbers and arrows on the remote control to navigate the call screen
• Use the keypad to dial the IP or ISDN number of the site you are calling. When dialing an IP
address, use the dot button on the remote control.
• Arrow to the “Quality” window to select call speed. Use the center button as an “Enter” button
• You can specify that you are dialing IP or ISDN, or let the system auto detect the call type
• Press the Call button to dial the call
• Make sure your microphone is not muted

Also, you may want to adjust the QOS on your firewall to make sure that your video calls get priority when it is in use.
