A b2b calls from A to B using uri address is sucessfull,video appears on Device A momentraly , but device B is good with video and audio. we are using fortinet FW and paloalto , and for the troubleshooting purpose ALL the ports is allowed from DMZ Fw ( paloalto) and internet fw ( Fortinet )
PCAP TAKEN FROM THE OUTSIDE INTERFACE OF VCS-EXPRESSWAY. WE SEE TWO-WAY VIDEO MEDIA , AFTER SOME TIME WHERE WE SEE MEDIA STOPPED BEING RECEIVED ON VCS-EXPRESSWAY FROM THE DMZ, LEAVING THE SCREEN BLANK WITH NO AUDIO.
We unchecked sip inspection, ALG and other's. but still we are missing something.

WE SEE MEDIA STOPPED BEING RECEIVED ON VCS-EXPRESSWAY FROM THE DMZ, LEAVING THE SCREEN BLANK WITH NO AUDIO check Traversal Zone status between C & E, check the CPU utilization on VCS-E, make sure the network path between VCS-E and VCS-C allowed the MTU size to be more than 1518 bytes to avoid drop large UDP packets.

A B2B video dropping or stopping after 2 seconds can be caused by several issues:
Network Connectivity: Poor or unstable internet connections can interrupt video playback. Ensure that both the server hosting the video and the user's connection are stable and have sufficient bandwidth.
Video Format and Compatibility: The video might be in a format or codec that is not fully supported by the playback system. Check if the video file is encoded correctly and compatible with the platforms being used.
Browser or Device Issues: Sometimes, the browser or device being used to view the video might have compatibility issues or need updates. Try testing the video on different browsers or devices to identify if this is the issue.
Server Performance: If the video is hosted on a server with performance issues or high traffic, it might cause playback problems. Consider optimizing server performance or using a content delivery network (CDN) to improve video delivery.
Video File Corruption: The video file itself might be corrupted. Re-uploading the video or using a backup file can resolve this issue.
