Video Conference on web

i have to create a voice conference for our website

what do you thing will be the best option

.Net or Flash ?

From stackoverflow

• ASP.NET is server side technology so I'm not sure how do you want to use it for voice conferencing, maybe you meant Silverlight?

  Flash is IMO a winner because 99% of your users already have Flash installed. Silverlight is, on other hand, only 25%.

  Searock : i have heard that flash has a good support for webcam and voice than Asp.net

• Check 'Adobe Flash Media Server' this is a really cool video and audio streaming server. You may check Flash Media Server Developer Center it :here
