How to build chat voice website via asterisk

Hi all,
I have live chat system on web. Now I want to intergrate chat voice (such as google, facebook) via asterisk. But I don’t know what I need to do that.
Please give for me some keyword to I can do that.
Thanks all

I don’t believe anyone on here can really answer or provide input on this. Your post is very broad and Asterisk has lots of functionality. You would need to investigate, test, and determine how exactly you would like it to work and if Asterisk is viable.
