BFCP interoperability with Lifesize devices

Currently there is a limitation with Lifesize devices (Icon series) calling into Webex meeting, CVI or directly to another Webex user and start to share presentation - the outcome is composite video (participant+sharing content) in one video stream hence dual screen cannot be used. The issue is due to BFCP server/client cannot be negotiated - Lifesize acting only as a server when initiating the call, Webex does not support being client. The workaround is to use H.323 but this will not work with the CVI since only supports SIP calls.
