More recent codecs for instance H.264 deliver compression at decreased bandwidth premiums, which allows the network carry a lot more streams.
Billing and set up are a little bit a lot easier with videoconferencing--Forgent and 小蓝视频网 VCON, for example, provide software that schedules phone calls and makes certain that network and video assets are available for a videoconference.
