Until a patch is developed tested and applied please follow these important steps:
It is important to note that when setting up users that will be using VVX500 who will have call recording enabled that video be disabled for their line.
Our Voice Engineering team is working on a patch and testing it out. Once that patch is applied video can be enabled at the same time as call recording.
Disable Video for VVX 500
(There are 2 places this can be done depending on the situation)
If there will be a limited set of users within the group or enterprise who will have call recording and a VVX500 this should be done at implementation through TFTP tool kit using the below string within the Polycom-user-MAC.cfg however, if Video is not needed anywhere in the enterprise it would be better to add this to the site config.
<video
video.enable="0"
video.autoStartVideoTx="0"
video.dynamicControlMethod="0"
video.forceRtcpVideoCodecControl="0"
video.quality="">
<video.callMode
video.callMode.default="video">
</video.callMode>
<codecPref
video.codecPref.H263="0"
video.codecPref.H26319981="0"
video.codecPref.H261="0"
/>
</video>
For an entire enterprise apply the above string to the Polycom-site.cfg this requires access to the TFTP server and may require you to open a ticket with support.
All adjusted phones will need to be rebooted.
The below confluence guide includes the configuration string to disable video for a VVX 500 as well as other useful TFTP strings.

Troubleshooting tip to determine if video codec is being negotiated.
After investigation we have found out why audio is dropping out on internal calls, which is a known issue with VVX 500’s involving the negotiation of video codecs. This has been found to cause audio issues on inbound and outbound calls. This has only been seen for internal calls negotiating the video codecs (below). You will not see video codecs for calls within the PSTN.
