Vonage has released a new app that allows iOS device users to make free voice-over-IP calls to their Facebook friends. Vonage Mobile for Facebook uses Facebook Connect to link users with contacts on their Facebook profile and then make free calls to any of their Facebook friends who are also using the Vonage Mobile for Facebook app on their iOS or Android device.
Users can make and receive calls on their iPhone or iPad or on an iPod touch using an external headset and mic. Calling is supported over both Wi-Fi and 3G networks anywhere coverage is available and calls can be made to any user regardless of location with no international calling fees or airtime charges—only data usage applies when using a 3G connection.
The application uses Push Notifications to allow users to receive calls when the app is in the background; it does not support iOS 4 background VoIP features at this time. Vonage Mobile for Facebook is available from the App Store as a free download.
