JAJAH has launched "JAJAH Buttons" that offer a click-through direct dial functionality to their VoIP service.

Designed to be used in emails, on websites, eBay listings, blogs and social networks, the buttons let the user call you, without you having to disclose your personal details.

The phone call to the caller is free and will typically cost around 2p to the button owner. Button owners can set times when they want to accept calls and can block numbers too.

With nothing to download, no headsets and no contracts, callers simply enter their own phone number (landline or mobile) and the call is connected.

The buttons can be added to your page "simply and easily" by visiting www.jajah.com.
