GLOBARANGE phones are hybrid 2-line 5.8GHz and DECT** cordless phones, supporting both landline and joip-powered VoIP services. The phones allow calls to be made and received via both the VoIP line and a regular landline connection from any of its expandable cordless handsets. This innovative phone provides a solution for consumers who want to enjoy the best of both worlds: the traditional landline phone and VoIP. Consumers can maximize the benefits of VoIP service, including free and low-cost calls as well as advanced features, without the hassle of being tied to a computer or the need for an external adaptor. At the same time, they maintain their current landline service and traditional phone user experience.

joip will power VoIP capability for GLOBARANGE phones without any software downloads or complicated setup procedures. With joip, GLOBARANGE users are given unlimited free calls to and from any other GLOBARANGE user worldwide with no service contract. The only requirement is broadband Internet connection through a router. joip also allows GLOBARANGE users to make calls to landline and cellular phone numbers at extremely competitive rates, while enjoying the most advanced features of VoIP technology.

joip offers a vast range of unique, affordable add-on features for GLOBARANGE phone users, such as ringtones, text messaging, the joip community directory, call forwarding to multiple numbers, advanced do not disturb options and voice message notification via e-mail. joip's inexpensive and user-friendly online management tools offer access to view and update GLOBARANGE phonebooks, call record details and more. joip also provides GLOBARANGE users with its advanced SoftPhone that acts as a virtual handset to make and receive calls through any computer, at home or while traveling.

"Panasonic is very excited to introduce consumers to our best technology working with deltathree," stated Nobuharu Akamine, Panasonic Communications Company's Managing Corporate Officer, "GLOBARANGE phones will make this innovative and attractive communication service available to customers worldwide."

"In so many ways, joip revolutionizes the traditional methods of telecommunications," stated Shimmy Zimels, deltathree's President and CEO. "Through the joip-enabled GLOBARANGE phone, the benefits of VoIP are being made widely available with no need to give up the old landline or use a PC. It's as easy as buying and using any new Panasonic phone."

deltathree's Consumer Group Director, Tomer Treves, stated, "The familiar and user-friendly experience offered by joip, coupled with Panasonic's vast distribution channel, creates a far-reaching foundation for the development of a global joip-enabled GLOBARANGE community."

GLOBARANGE phones feature Call Waiting, Caller ID, handset speakerphones, handset expandability, a large, easy-to-read three-line backlit LCD, and a tri-color incoming call-status indicator light. GLOBARANGE phones will be available this summer.
