MontaVista Linux Powers New IP Phone and Enterprise Media Exchange

Provides Robust Platform for ZultysZIP 4x4 and MX1200

SUNNYVALE, Calif., March 31, 2003 — MontaVista Software, Inc., the company powering the embedded revolution, and Zultys Technologies, which designs and manufactures products that integrate telecommunications and data communications for enterprise networks, today announced that MontaVista™ Linux® Professional Edition 3.0 is the chosen operating system for two newly launched Zultys devices, the ZIP 4x4 IP phone and the Zultys MX1200. The ZIP 4x4 integrates an IP phone with a multi-port switch while the MX1200 is the industry’s first enterprise media exchange product to deliver sophisticated PBX (private branch exchange), switch, router, and Internet gateway functionality in a single box.

“We considered several proprietary embedded RTOSes, but concluded that we could save development time and costs using Linux, and were also able to take advantage of available open source software code,” said Iain Milnes, president of Zultys Technologies. “MontaVista has an excellent reputation in the Linux community and it authored the preemptible kernel patch and real-time scheduler — two Linux extensions that are very important to us. Another key decision point was that MontaVista Linux Professional Edition supports the IBM PowerPC 440GP, which was our target platform for the MX1200.”

Both products are based on open standards such as Linux and SIP (Session Initiation Protocol), and are capable of performing multiple functions.

The MX1200 fully integrates voice, data, video and fax into a single 2U box with one software interface. It combines the functions of an Internet gateway with a PBX, and adds support for video calls as well. It is designed to be scalable, allowing enterprises to expand up to 1200 users without the need for additional hardware.

The ZIP 4x4 integrates the functions of a managed switch with a business phone, and adds an address book, a calculator and a speakerphone. It features four call appearances providing four simultaneous incoming and outgoing calls, and four Ethernet ports allowing devices such as laptops and PDAs to obtain line-speed connectivity to the LAN through the phone.

“The Zultys MX1200 and the ZIP 4x4 IP phone represent the next generation of advanced Internet-connected business communications devices,” said Trent Winegar, vice president, worldwide sales, MontaVista Software. “MontaVista Linux gives Zultys a robust, open platform allowing it to bring new and innovative products to market quickly at lower total development costs.”


MontaVista Linux Professional Edition 3.0 is the latest version of the company’s cutting-edge embedded operating system and development platform. Offering enhanced networking capabilities, increased tools coverage and the latest Linux technology, this newly updated version of the product enables embedded equipment manufacturers to develop a broad range of devices.

“The Zultys MX1200 is based on IBM’s PowerPC 440GP microprocessor, which was created for mid- to high-end devices that require a rich mix of embedded peripherals, and which MontaVista was among the first companies to support,” said Lisa Su, director of PowerPC and emerging products, IBM Microelectronics. “We believe that MontaVista Linux coupled with IBM’s PowerPC processors will provide Zultys with a consistent, scalable, development road map for its future products.”
