Twitter will Make Phone Calls

Twitter developers continue to search and find new ways to leverage the popular microblogging service. Soon you’ll use Twitter to make phone calls. The communications company Jajah has released a beta of its "Tweet-to-Talk" service, JAJAH@call, that the company says will give the opportunity to users making calls via Twitter: the service is free.
The "@calls" are made without showing the caller's phone number and, it will be sufficient the Twitter username for the callers, there will be no necessary to know the number of the person they want to call. Jajah says you can use the service to make a call by sending a tweet (Twitter message) with "@call @username". If that person follows you on Twitter, a free 2-minute call (it’s is the verbal equivalent of a 140-character tweet) will be start to talk.
