Fring is a great application for video call and chat. It support many instant messengers. Well I use it on my htc evo to video call and chat with both messenger and Skype. You can test both audio and video. Also you can have multiple chats or calls, add friends, and integrate you phone book. On the settings it has an option for automatic startup. To conclude you can contact them for support if you have any problems. It works, its simple, and its flexible. What more you want?
