Place a Phone Call…Via Twitter

Twitter users will soon be able to make short phone calls for free directly through the micro-blogging service. JaJah, an Internet telephony company that allows you to make VoIP calls using your landline or cell phone, is launching the beta version of its new Twitter calling service, named @call.

Jajah says its service will work whether you're using Twitter directly via its site or are logged on using a third-party client like Seesmic. Jajah says you'll even be able to make calls when using Twitter clients like Tweetie and TwitterBerry on your smartphone.

To place a call via Twitter, you and the person you are calling must be Twitter users and Jajah users (you can sign up for both services for free). The person you want to call must be following you on Twitter, and you both have to sign up for the @call beta.

Jajah says it is keeping phone calls to two minutes, because that amount of time is the "equivalent of a verbal tweet." Jajah says your phone number will never be revealed when using @call.
To sign up for Jajah's @call Beta program, you must first register with Jajah and then send an e-mail to twitter@jajah.com. You can also follow Jajah's @call program on Twitter.
