The Call Me application is a moveable button that can be dropped anywhere on Facebook that accepts attachments.
This enables users to embed their Call Me button within Facebook messages, post their Call Me button on to their friends' walls, or drop their Call Me button on to Facebook group and discussion boards.
The Truphone Call Me application is available to all Facebook users. Users do not need a Truphone account or a special phone in order to use the application.
Facebook users adding the application choose the number on which they would like to take inbound calls and get a Truphone Call Me button on their profile.
A different number may easily be selected at any time, including Truphone mobile numbers, US mobiles and landlines, UK landlines, and any VoIP SIP-based phone.
