Picture 45 Phone Calls Come to Twitter. JAJAH, a VOIP company, will announce the beta-launch of its Twitter calling solution, JAJAH@call tomorrow.

You’ll be able to make phone calls via Twitter free of charge to anyone in the world, so long as they follow you back and have JAJAH accounts.

@calls are made without revealing your number and without needing to know the number of the person you wish to call – all you need is their Twitter username.

The beauty of JAJAH is that it uses the Internet to connect two standard phones, thus implementing both the advantage of the Internet as a low-cost service and the comfort of using a regular telephone device.

How does it work with Twitter?

To make a call simply send a tweet with “@call @username” where the ‘username’ is the Twitter name of the person you wish to call. If that person follows you on Twitter, a free two-minute call – the verbal equivalent of a Tweet – will be initiated.

This is Potentially Huge

It’s no secret that Twitter aims to become a communication standard. With the integration of telephone calls, it brings the service that much closer to achieving that goal by ensuring that people are only connected to people they want to be connected with, and have the option of either voice or text communication – in effect, almost replacing the telephone number and text message at one fell swoop.

Communication service providers have caught onto the fact that Social Networks have the potential to replace communication methods of the last century, and not just via text. Facebook users will also now be able to communicate with each other via voice using a third-party application from Vivox. However, I foresee Twitter/JAJAH’s implementation to have greater success, primarily due to the simplicity and open nature of Twitter, in contrast to the rather laborious, often frustrating, experience of adding of applications on Facebook.
