dynamicsoft Service Engine Platform Accelerates Deployment of Real-Time Voice Services
PARSIPPANY, NJ -- (MARKET WIRE) -- 06/30/2004 -- dynamicsoft, a premier telecommunications infrastructure provider, leading the delivery of push-to-talk and other real-time voice, messaging, video and presence services, today announced that Unefon, a leading Mexican mobile telephone operator, has deployed the first nationwide push-to-talk service in Mexico, leveraging the capabilities of the dynamicsoft Service Engine platform to support real-time IP-based communications services.

Unefon's new offering is a walkie-talkie style service called RadioUnefon(SM), which gives customers a quick, convenient way to communicate one-on-one or in groups with the simple push of a button. Ideal for short "get in, get out" conversations, RadioUnefon is an efficient and cost-effective way to quickly access co-workers, clients, family and friends anywhere on Unefon's CDMA network. With 1.8 million customers in 16 of Mexico's key metropolitan cities, Unefon launched this new nationwide service in June.

"We are committed to offering our customers a broad array of the most feature-rich services available today. We recognize our subscribers' communications needs are rapidly changing and we see an increased demand for services that provide instant communication," said Adrian Steckel, chief executive officer of Unefon. "dynamicsoft has a proven track record, having built the infrastructure necessary for the highly successful Sprint PCS Ready Link(SM) deployment. Within three months of placing the order, we are already offering our customers a cost-effective, carrier-class, push-to-talk solution. This will be the first of many new service offerings that Unefon adopts in order to enhance the user experience."

"We recognize that operators want to offer a wealth of new services while leveraging their existing network infrastructure," said Patrick Farley, chief executive officer at dynamicsoft. "The dynamicsoft Service Engine platform not only provides a proven push-to-talk solution that dramatically accelerates time-to-market, but also supports the next wave of compelling new features such as presence-enabled push-to-talk, push-to-video and push-to-voicemail, driving both subscriber growth and revenue per user."

"Trends indicate that the demand for richer ways to communicate will grow dramatically," said Wally Swain, principal analyst of Yankee Group's Wireless/Mobile Latin America Group. "Presence-enhanced push-to-talk and push-to-portal are just two service enhancements to push-to-talk I expect to see in the coming year."

The dynamicsoft Service Engine™ product is a standards-based software platform that enables a broad set of value-added IP-based services to be delivered and managed across wireless and wireline networks. The Service Engine platform consolidates common functions such as customer data distribution, authentication, authorization, provisioning and service interaction, making it possible to quickly create a wide variety of services with maximum re-use of assets at minimal expense. The dynamicsoft Service Engine platform is a core component of the Sprint PCS Ready Link service and is fully integrated with available Push-to-Talk application servers and handsets.
