tekVizion PVS, Inc., the Packet Voice Specialists(TM), announced today the appointment of Terri Albers Griffin to the position of president. In this role, Griffin is responsible for management of the company, overseeing operations, finance, and marketing. The addition of Griffin as president is an important step in the company's expansion strategy to meet growing customer demand.

tekVizion(TM) was founded in 2000 as a developer and integrator of telecommunications software and services. In 2002, the company began focusing exclusively on delivering innovative Packet Voice Solutions(TM) that help service providers quickly design, deploy, and support next-generation telecom services while maximizing their investment in their legacy systems. tekVizion offers a full range of services including business and technology consulting, interoperability testing, integration services, and custom software development. The staff's experience spans next- generation and legacy product development, integration, and support. This unique collection of knowledge and experience allows the company to help service providers bridge the gap between circuit and packet-based technologies in order to create multi-vendor solutions that result in revenue-generating products and services.

Griffin and many of the tekVizion employees were key players in the Sonus Networks' Open Services Partner Alliance (OSPA) and the telecom technologies' INIP Powered lab. These programs, widely regarded as the industry's premier partner programs, gained their reputations by providing the most comprehensive lab environment for integrating and testing end-to-end, packet-based network solutions for service providers. Griffin was instrumental in the development and implementation of these programs while serving as vice president of marketing at both Sonus and telecom technologies.

"We are very proud of tekVizion's success to date, having achieved consistent profitability resulting from a foundation of successful project engagements and long-term contracts with large carriers. We are now entering a new phase during which we are expanding the company and our business development activities. We are very pleased that Terri is joining us at this time, as her industry knowledge, experience, and leadership capabilities will greatly strengthen our team and provide tekVizion with a solid foundation for accelerated expansion and growth," said Phillips. He previously held the title of president and CEO, and now as CEO will focus on setting the strategic direction of the company and business development activities.

Prior to joining tekVizion, Griffin was director of marketing for Cisco Systems, Inc., where she utilized her solutions experience to develop and execute the strategy for Cisco's southern area. Before Cisco, she was vice president of marketing for both Sonus Networks and telecom technologies. Griffin also held the director of marketing position at ODS Networks, Inc. (now Intrusion.com), a leading manufacturer of data networking and security products, as well as EMASS, Inc., a leading developer of specialized storage management software and libraries. She was also a software engineer for leading defense contractor E-Systems (now Raytheon Company). She holds a bachelor's degree in mathematics and a minor in computer science from Stephen F. Austin University in Texas.

"I am very pleased to be joining tekVizion at this time. There is a tremendous demand for the specialized knowledge, experience and services that tekVizion has to offer both service providers and vendors seeking to provide comprehensive, carrier-class solutions. I believe this team is uniquely qualified to provide these services and I look forward to working with them as we continue to expand our capabilities and customer base," said Griffin.
