We are facing a video disconnection issue in one of our spoke location during a multiparty call.
We had a Video Conferencing between 3 locations (Head Office(India) - IP address 192.168.1.224, Spoke (India)- 192.168.14.125 and USA - 192.168.24.201 )
Video Conference Device Model:
(Head Office(India)) - IP 192.168.1.224 - Polycom group 500
Spoke (India)- 192.168.14.125 - Polycom group 500
USA - LifeSize Series
Connectivity Details :
Head Office (192.168.1.224) to Spoke ( India - 192.168.14.125 ) is via private MPLS Connection.
Head Office (192.168.1.224) to USA (192.168.24.201) is via Site to Site VPN Connection.
How the call is connected :
Spoke (India) to the Head Office is first connected by dialing and from head office the USA Location is connected to make it a multiparty call.
Issue in details:
In Spoke (India - 192.168.14.125) , "Only Video is frequently getting disconnected" during the meeting. No problem is with audio. Initially it is working fine but after some minutes in spoke india vc video is disconnecting.
We have monitored the issue a little deeper , where we’ve found that when the “Video RX” changes to “CIF Format” video got disconnected, again when the format is changing to 960 X 544 or different the video is stable and working fine.
Please find the attachment of cif format and issue
Note: In the Head Office(192.168.1.224) and USA(192.168.24.201) ,there is no issue at all.
Please check and suggest what will be the problem ?!!
Hello @Networkadmin Microlabs
I suggest you follow this from the Video FAQ:
What is your minimum downspeed rate under Service Config>Conference Management Settings>Conference Settings? I ask because if the video endpoint call rate drops (and I am assuming it is b/c you see it negotiate CIF) you could have a situation that the rate is too low to maintain the video stream. I have mine set to 512 because anything less than that starts to produce lesser quality resolutions
