Webphone development

Apr 23 2012 9:54 AM

Hi,

I'm a beginner developer and I wish to use this sample program (voip-sip-sdk.com/p_399-flash-webinar-web-conference-voip.html) to build a webphone for webinars in .NET.

Please help me a little! Which development environment should I use: Visual Studio 2010(recommended) or Adobe Flash Builder 4.5?
