We have the Polycom VVX500 phones with the optional cameras installed. Although the cameras are activated and the video is visible on its respective display, when calling other like phones in the office, video of the caller and callee does not display and a video icon appears with a cross on top of it.
This would be a great feature to add to the platform. With SIP telephony growing at an ever increasing rate and the ever descending price of IP phones capable of supporting video calls, there is a need to support direct video calls. We have recently released a line of video intercoms that support the H264 codec and our customers would love to continue to use Ringcentral for their VoIP needs.
06-22-2017 POSSIBLE WORKAROUND::: We are testing using RingCentral Meetings as our internal video support vehicle, becuase we have 2000+ Users on the RingCentral account. This would offer anyone with a RingCentral account that has Meetings attached, the ability to do screen sharing both local and remote video if the remote user grants session access to control their screen, etc. as part of a Meeting instead of doing it on the phone hardware.
You can use the CyberSoftphone (found here http://www.cyberdata.net/voip/011410/ )on your PC to receive calls from the CyberData Video Intercoms or you can set it up at a point to point device http://www.cyberdata.net/assets/011410/931405A_Video_Intercom_Point_to_Point.pdf
