NEW ZIP  4x4 FROM ZULTYS INTEGRATES IP PHONE AND MULTIPORT SWITCH 

Based on SIP, the ZIP 4x4 delivers all the functions of a business telephone
and provides four Ethernet circuits for connecting to the network and
additional devices

SUNNYVALE, CA, 24 March 2003 - Zultys Technologies today announced immediate
availability of its ZIP 4x4 IP phone. The ZIP 4x4 is built 100 percent on
open technologies and runs on a highly stable real time Linux operating
system. It is compatible with any IP telephony system using SIP (Session
Initiation Protocol), with support for advanced features such as line-rate
Ethernet switching, voice encryption, and five-way conferencing.

"Four by four" in the name refers to the phone's four call appearances and
four Ethernet ports. The four call appearances provide four simultaneous
incoming or outgoing calls. The four Ethernet ports allow devices such as
laptops and PDAs to obtain line-speed connectivity to the LAN through the
phone; no other IP phone available today has a built-in switch with more
than two Ethernet ports.

"The adoption of VoIP in the enterprise will be driven by the availability
of products such as the ZIP 4x4, that offer advanced functionality and
interoperability with any IP system or platform," said Brian Strachman,
senior analyst, In-Stat/MDR Research. "As SIP becomes a standard of choice
for enterprise VoIP applications, products that combine data handling
capabilities, security, ease of use and SIP-compliance will not only win
out, but perhaps lead the adoption of VoIP in the enterprise."

With Zultys' ZIP 4x4, organizations can realize the business benefits of
simplified installation, provisioning, and management of an IP phone system.
Providing both voice and data communications to the desktop requires only a
single wire from the network room. For companies with one Ethernet
connection already at the desktop, this means deployment of VoIP requires no
disruption or rewiring of the network. For new offices, this means greatly
reduced cost of wiring a station for both voice and data. Regardless of the
type of deployment, the required number of switch ports in the network room
is halved, with direct reductions in cost, power, and space. Also beneficial
is the rollout process for the ZIP 4x4, which is streamlined so that
administrators can provision a phone within minutes. The phone retrieves its
software and configuration from a TFTP server and locates SIP servers using
DNS-SRV. An end user relocating within the enterprise needs only plug the
phone into another Ethernet port and he or she is instantly provided with
the same voice and data services. These processes for provisioning and
relocation result in minimal effort for moves, adds, and changes (MACs).

"The release of the ZIP 4x4 again demonstrates that we have a clear
understanding of the needs of telecom and datacom user by integrating
multiple functions into a single product," said Iain Milnes, president of
Zultys. "Its design, functionality, and method of deployment result in
increased productivity for both end users and administrators."

Earlier this year, Zultys announced the release of the MX1200, the world's
first enterprise media exchange. Also based completely on open technologies,
including SIP, the MX1200 fully integrates voice over IP (VoIP), data,
video, and fax into a single, compact 2U box. The ZIP 4x4 is a natural
extension of the company's strategy to offer a suite of fully interoperable
and easy to use VoIP products to the enterprise.
