I have found the following issues with Group Series 6.1.7 and 126.96.36.199 and Zoom
1. Polycom Group Series 500 (GS 500) calls into a Zoom meeting H323 through Zoom CRC and received a black content channel when a Zoom computer client is sharing content during a GS joining. Some GS packet captueres show incomming rtp packets on the content channel, at other times there are no content rtp packets until the laptop stops and restarts sharing content. In some of my test the GS joins and receives content correctly, but when the Zoom laptop cilent stops sharing and restars the share the GS does display content just a black channel.
At times instead of a black content channel the GS does not recevie a content stream instead receives content on the primary video stream. Zoom has indicated that Zoom will share content over the video channel if it detects and issue or a legacy endpoint cannot receive a content channel.
2. Polycom Group Series 500 (GS 500) calls into a Zoom meeting H323 through Zoom CRC and received a black primary video stream but the GS video channel is receving UDP packets but does not seem to decode them and sends Zoom 100's of fast update requests.
I have a case open with Zoom and Polycom and they are able to replicate this issue with Group Series but not HDX endpoint. I feel we have ruled out our network and firewall which is a Palto Alto physical 5600 and 7000 series.
Is anyone else experiencing these issues?
This was reported to Polycom whom reported it to Zoom and as of this week the issues seem to have been fixed.
