MARLBORO, Mass.--(BUSINESS WIRE)--Feb. 2, 2004

Telica(R), Inc., an innovator in next generation VoIP switching, today announced that Navigata Communications Inc., a member of the SaskTel group of companies, has deployed multiple Plexus(TM) 9000 switches to support long distance, 800 and prepaid calling services across its nationwide Canadian network.

Navigata, a Canadian service provider, offers its customers cost-effective, reliable voice, data and Internet services. The company operates a national network and has major hubs in Vancouver, Calgary, Toronto, and Montreal. Since its founding 45 years ago, Navigata has distinguished itself through its superior customer experience, adoption of new technology and network expansion to meet the changing needs of its customers.

Integrating Telica's solution into its network enables Navigata to cap its investment in embedded TDM equipment and expand its services to include prepaid calling and 800 services using AIN 0.2, with next-generation switching technology. By utilizing the Plexus 9000, Navigata realizes compelling operational and capital savings through a smaller footprint, lower cost per port and reduced power costs.

"Navigata takes great pride in implementing communication solutions that give us the flexibility to accommodate our customers' diverse needs," said Tom Laird, president and CEO of Navigata. "Integrating Telica's switching technology into our network will allow us to offer our customers greater choice and flexibility, and will help position us well in this dynamic environment."

The Plexus 9000 is a key component of Telica's PLUS(TM) second-generation softswitch family. Telica's Plexus 9000 is a carrier-class voice softswitch that offers an industry-leading 80,000 port density on a stand-alone basis. When deployed as an element of the PLUS architecture, the Plexus 9000 enables carriers to build networks of up to 500,000 ports. Carriers utilizing the PLUS architecture can deploy Class 4 tandems or Class 5 end offices, using TDM or IP for trunking or access in one highly scalable network. The unparalleled density and architectural deployment options offered by PLUS, coupled with support for both legacy and converged voice network architectures, provide the highest level of flexibility for domestic and international service providers.

"Navigata has a stellar reputation as an innovative service provider, and we look forward to continuing to work with them to address their customers' evolving needs," said John St. Amand, Telica's president and CEO. "Our solution offers a powerful combination of rich features and services, enabling providers to grow their businesses efficiently and quickly while also saving them significant operations costs."
