Besides, users who don't know much about Vo IP tend to subconsciously interchange the words Vo IP and Skype.
It works on Windows and Mac computers but also mobile devices like Black Berry, i OS, Android, Nokia, and Kindle.
You can also join chat rooms, send stickers, make audio only calls, and set up group chats.
This lets you not only login but also easily reach the contacts you already have stored in Gmail.
On top of that, though, Google Hangouts is actually pretty intuitive and easy to use.
Skype is the most popular app for voice and video calling.
In the mobile market, Skype has since long been dethroned by Whats App and Viber, but it still remains the most prominent tool for free communication on computers.Since Nimbuzz is a video calling program, you can only video call someone if they are also using the app (be it on their computer or mobile device).However, their audio calling feature can actually be used with regular phones too, for a small fee.Once you're all setup, you can (almost) instantly connect with family, friends, co-workers, or anyone else who is using the same app.After you install one of the free video chat apps you see below, there are just a few things you need to make sure you have: an active internet connection, ample bandwidth, a webcam, and an audio input and output device (microphone and speaker).It works so much like a regular phone that it should be one of the easier apps to use from this list. You can download the app on other devices like Android and i OS, but those devices can only use the text and voice calling features.
