SAN JOSE, CALIF. and DALLAS, TEXAS - March 13, 2001 - DataVoN, Inc. (a wholly owned operating subsidiary of DTVN Holdings, Inc. OTCBB: DTVN), a nationwide provider of packet-switched network telephony services, announced today it had selected the ipVerse ControlSwitch as its core softswitch platform and Cisco gateways, routers and switches to deliver next generation IP services to its customer base. DataVoN anticipates initial deployments by May 2001. Upon full deployment, up to 260,000 softswitch controlled packet telephony ports, DataVoN would have the capability of managing more than five billion minutes per month in network traffic.

With the ipVerse ControlSwitch acting as an intelligent operating system for converged services and Cisco high-density, carrier-grade VoIP gateways, DataVoN expects to enhance its ability to offer competitive toll quality voice services in addition to an extensive array of carrier-grade services for the wholesale market. DataVoN's strategic objective is to aggressively build a next generation IP managed network by maximizing the lower cost of originating, transporting and terminating traffic across the network, thereby capitalizing on the market opportunity resulting from the rapidly increasing demand for a converged voice and data network. DataVoN believes the ipVerse ControlSwitch will enable it to achieve its service objectives, including future delivery of new and enhanced services to its carrier customers in any size market.

"I believe the combination of the ipVerse ControlSwitch, along with Cisco gateways will serve an essential role in our integrated packet network by giving us an all IP network that is more scalable, reliable and cost-efficient. The ipVerse ControlSwitch open services architecture provides us the ability to quickly implement new, IP-based services, such as unified messaging, prepaid calling and conferencing. We anticipate deploying the services in our existing markets, and future domestic and international markets," said Hugh Simpson, Chairman and CEO of DataVoN, Inc.

"The ipVerse ControlSwitch is expected to enable DataVoN to build one efficient packet network for all its services offerings, rather than deploying separate voice and data networks that require traditional class switches. Utilizing the ipVerse ControlSwitch's distributed softswitch architecture, DataVoN anticipates cost savings for its network expansion through both reduced capital expenses and ongoing operational expenses, as compared to traditional circuit switching. This network's flexibility and pricing advantage is what differentiates DataVoN in the very competitive telecom marketplace," said Simpson.

"By choosing an open packet telephony architecture, and relying on Cisco gateways, routers and switches, DataVoN ensures its customers it will deliver the same carrier-grade service they've come to expect from the PSTN," said Randy Brumfield, director of marketing at Cisco Systems.

DataVoN's network will be based on the following Cisco equipment; the Cisco MGX 8260 gateways; the Cisco 7500 series routers and the Cisco Catalyst 4000 series switches.

In order to meet the high traffic volumes of its customers, DataVoN expects to significantly expand its current network by deploying high-density voice gateways across the US and in select global markets. DataVoN will also have the option to interconnect with other packet voice providers. This internetworking flexibility is made possible by ipVerse ControlSwitch's unique multi-protocol platform that supports next generation protocols, such as MGCP, H.323, IPDC and SIP, in addition to many traditional telephony-signaling protocols, such as SS7 and ISDN-PRI.

"Since its founding, DataVoN has developed a significant base of business and demonstrated the capability of operating profitably with internal funding," said Art Klein, President and CEO, ipVerse, Inc. "The migration to a softswitch-based converged network is expected to add profitable new services and strengthen DataVoN's position in the marketplace. We are thrilled that DataVoN has chosen ipVerse's multi-vendor softswitch as a part of the foundation of its next generation voice services strategy, and we look forward to building a strong partnership."
