Zoom supports H.239 ITU standard for content sharing on a H.323 device and BFCP for content sharing on SIP device. This allows you to view a video stream as well as a content stream through your H.323 or SIP device if you have dual monitors. H.239 and BFCP are ON by default, and can be toggled with the instructions below.
