We have 2 Group 310 VCs (V. 18.104.22.168) with SfB option we can't get to show video when joining a meeting. There is only audio and the display shows a crossed out camera. When calling a PC with MS Teams or Skype they both show video and audio if the receiver answers the call as a video call.
Also, it is not possible to call any of the 310 VCs through Skype, they don't seem to receive incoming calls.
System status reports SIP, Directory and calendaring as OK (using Office365 accounts).
Any idea what the problem might be?
PS. for now we are using standard user accounts not room accounts
you are 100% sure you have installed SfB key on both Groups? Normally this behaviour (Audio only) is a hint for the missing option. Please doublecheck your Group options for activated SfB Interop license (admin settings > general settings > options).
I got this partially sorted, one one of the ends I get both video and audio but on the other I only get audio and a black screen. The end not transmitting video is behind a firewall with SIP ports redirected to a VoIP PBX, cand this be related to our problem?
