Jajah, a US-based IP telecommunications company, has launched new services for Windows Mobile, BlackBerry and Symbian. The new services, which enable VoIP calls to be made either via WiFi or over the cellular network, are offered as white label solution to enable carriers and non-carriers to launch the service under their own brand.

Jajah claims that its platform incorporates everything a company would need to launch the service immediately under their own brand. This includes the application itself, plus the entire suite of management services, from termination of the calls and quality control, right through to billing and processing payments in 200 countries around the world.

The Jajah application for BlackBerry gives all BlackBerry users the ability to make Jajah VoIP calls directly from their device. Available as an over the air download, via the desktop manager or from a corporate BES server, the application adds ‘Jajah Call’ to the phonebook menu. Alternatively, users can open the Jajah application and type in the phone number.

Designed for making VoIP calls over a WiFi network, Jajah for Symbian gives anyone with a phone running Symbian s60 the ability to choose whether their international calls route over the Jajah IP network or the standard cellular network. The application automatically detects the presence of a WiFi network and offers the choice to use Jajah when a long distance phone number is dialed (either manually or via the address book).

Jajah for Windows Mobile is a full SIP over HSDPA/WiFi mobile VoIP system. Currently deployed by Japan’s eMobile, the Jajah service is expected to turn any device into a fully functioning VoIP phone.
