QuicklyChat

QuicklyChat is a great tool that provides a quick way for coworkers to video chat with each other when they're working remotely.

The biggest difference between QuicklyChat and conventional video communication is that QuicklyChat auto-answers incoming calls when the recipient is available.
Incoming connections are displayed in an unobtrusive notification window, so you can keep working if you're in the middle of an important thought, without having to think about how to respond to an incoming call.
The app uses SmartStatus to let your friends know whether they should initiate a conversation with you.
