I'm developing an application in Unity/C#, a social application, where you can meet friends, post messages, chat, and so on. I'm not calling this a "game" because I intend this to be something where you don't need to shoot, or destroy, or earn money, or all other game stuff. The application is on: http://www.meeworld.com
This application I intend to be for android tablets.
Now I want to enable Voice Chat. What library should I use? Do you know some library that can be used with Unity? I want something that works very well on tablets and can work well with more than 2 people.
