Hi, I need to develop a webinar in Flash and I’m using a sample program provided by Ozeki VoIP SIP SDK for this purpose(you can google this: voip-sip-sdk.com/p_399-flash-webinar-web-conference-voip). Please help me a little! Which development environment should I use: Visual Studio 2010(recommended) or Adobe Flash Builder 4.5? Thanks for your help in advance! Thomas
