Audio,Video ,Text chat and Data Collaboration Web Application

Audio,Video ,Text chat and Data Collaboration Web Application

I am Having the requirement to do Features Like  

Audio,Video and Text Chat and also File Transfer Features as a Web application Project ( for eg, Skype in web application).

I am Analyzing The SIP SDK Providers like

"Ozeki VoIP SIP SDK " , "AVSPEED Web Video Conferencing SDK"

to do the application in Silver light. I am slightly confusing to do all these features and i hope that i am going in the right direction.

I would like to know any other methods or technologies to follow to do all these features in web application. Can I have any resources or articles regarding this. any help will be greatly appreciated.

Thanks & Regards

Vijay
