I upgraded from X.7.1.1 to X.8.1.1. I no longer get video or audio across traversal. everything works internal. Video/Audio also works if registered to the expressway calling outside of network. It is only traversal link. I have asked them to confirm the ports 50000 and 50001 are opened. I have also now asked them to open the full port range 36000 – 59999 UDP . I have tried changing the port range for traversal media. to full range. I did not leave it this way. I would have had to change the Ephemeral port range. So it is back to the media port range is back to 50000 - 54999 UDP. Any suggestions?
