Video Teleconference (VTC) and VLC

[cardgame]

we need to record VTCs from Polycom equipment. Polycom says they can output h.264 which should be a problem, but the older VTC equipment uses H.323. Has anyone ever worked with h.323 streams or know of a product that can convert h.323 to a network stream that is usable by VLC?

Thanks.
