A Google returns this 1993 article in which the product is mentioned:
Just before Christmas, BT launched its VC7000 conference unit
(made by
Tandberg in Norway). This is a low-cost digital videophone, with a
25-centimetre colour cathode-ray tube screen which is switchable
between 64 and 128 kbit/s working. It costs ?7500. BT puts the
cost of
an hour's video call at 128 kbit/s to the US at ?168, but Mercury
promises to undercut this by nearly ?40. Call cost can be halved by
switching the phone to work at 64 kbit/s, but most serious users
prefer to pay more to get the better pictures and clearer sound
available from 128 kbit/s working. The British telecommunications
giant GPT is also selling 64-128 kbit/s systems, with screens
measuring up to 70 centimetres, for around ?40 000.
