Established in 1988, Huawei Technologies is a high-tech enterprise
which specializes in research and development (R&D), production and
marketing of communications equipment, providing customized network
solutions for telecom carriers in optical, fixed, mobile and data
communications networks. Huawei's customers include China Telecom,
China Mobile, China Unicom, China Netcom as well as Thai AIS, South
Korea Telecom, SingTel, Hutchison Global Crossing, PCCW, Telemar

Huawei's products can be divided into the following categories: fixed
network, mobile network, data communications and optical network ---
ranging from switching, optical transmission, intelligent network,
support network, GSM, GPRS, W-CDMA, cdma2000 1x, videoconferencing to
other key telecom technology fields. Most important of all, Huawei
products are based on its independently designed ASIC chips. Its ASIC
designing capability is among the most advanced in this field
worldwide. This allows Huawei to consider the needs of its customers
from start to finish, from the chip to the network.

Of these two, Huawei is reportedly the most technologically
sophisticated. I have a few emails sent out to various manufactures of
components needed to manufacture video conferencing equipment and if I
get a response which lists other companies I will post them here as
well.
Thanks,
