I'm looking for a good group chat app that I can add to my asp.net webform application. It doesn't have to have instant messenger, but that would be nice. As long as private rooms are part of it. Also something that supports mobile devices.
Voice chat, like TeamSpeak would be great.
Any suggestions? I don't care if it is paid. I just want something that I can customize into my existing database of members and support many users. It must support sql server.
It would be nice if it supported video chat, but not required. As long as it allowed custom little icons of the actual user's thumbnail. The one I have has all that, but I'd like to see what else is out there, since it's time to update for windows 8 anyway, and the upgrade is $623.
