Issue Description

NGAF deployed as route mode. Video conference unreachable and didn’t show image.

Handling Process

  • Get confirmation from video server vendor that they have their own NAT function. (or alg application layer gateway).
  • Disconnect the video conference first, then disable the  [H.323 port] and [SIP port], click [OK] and wait for another 5 minutes.
  • Then, connect the video conference and find that the communication is normal.


Root Cause

The video conferencing server or terminal had enable ALG function and  AF does not require to enable ALG conversion.

Solution

When configuring a video conference, if the video conference server or terminal performs the ALG function, you do not need AF to perform ALG conversion. Require to disable SIP and H.323 port.
