JAJAH, a venture-backed VoIP start-up based in Mountain View, California, is unveiling a Mobile Suite that will allow consumers to make free long-distance and global calls directly from their mobile phones. 
JAJAH establishes phone-to-phone connections through the Internet for cheap calls. The process is simple: callers type in their own number (landline or mobile) at http://www.jajah.com/ , and insert their desired destination number. JAJAH then rings both parties on their actual phones.
The company said its JAJAH Mobile Suite will allow virtually any mobile phone to make JAJAH calls easily. Starting with Symbian and Java-based J2ME phones and soon with text messaging and smart-phone/browser solutions. JAJAH said it can enable virtually any cell phone, regardless of carrier, manufacturer or existing agreement to make these calls. It works existing mobile phones and plans — no new number, no new agreement.
To use the service, you first need a JAJAH account, which is free and without obligation.
