Zello is based on peer-to-peer architecture and works behind most firewalls and NATs. The software is lightweight (installer less than 1 Mb) and unobtrusive. Normally it runs in the background and can be activated with hotkey without switching the focus or popping up the application window.

The advantages of Zello over existing messaging systems include speed, asynchronous style and voice messaging.
