TCS Unveils Industry-Leading MSAG-Based Routing for VoIP 9-1-1 Calls

VoIP Service Providers Are Now Able to Meet Recently Requested Public Safety Requirements

ANNAPOLIS, MD -- (MARKET WIRE) -- June 13, 2006 -- TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications and the nation's leading VoIP Positioning Center (VPC), today announced it has incorporated a Master Street Address Guide (MSAG)-based routing feature in its existing Voice over Internet Protocol (VoIP) VPC. TCS' new MSAG-based routing feature facilitates the routing of 9-1-1 calls that are made from a VoIP Service Provider (VSP) subscriber to the Public Safety Answering Point (PSAP) emergency call centers. This solution applies to static and nomadic VoIP emergency calls.

"With the introduction of this new call routing feature, TCS demonstrates a commitment to improving the quality of E9-1-1 service for VoIP providers and PSAPs," said Roger Hixson, NENA Technical Issues Director. "This development also supports the intent of NENA's recent VoIP Position Statement on use of MSAG-based call routing."

Until now, 9-1-1 VoIP call routing has typically been accomplished by converting a caller's address to a latitude and longitude (lat/lon) that is then plotted on a map of PSAP Emergency Service Zone (ESZ) boundaries. Each ESZ is identified with an Emergency Service Number (ESN). The call is routed to the PSAP that serves that ESN. This solution remains effective in areas where MSAGs are not available, but it is prone to inherent errors related to the accuracy of the lat/lon conversions and the compatibility of the various map formats used within Public Safety. It also requires a significant amount of maintenance to keep ESN maps accurate.

The ability to route calls using MSAG routing positively addresses the concerns of PSAPs that have previously delayed deployment of VoIP service due to concerns over accuracy of the ESZ mapping solution. The MSAG database contains street names and house numbers that are associated with ESNs. By comparing a caller's specific street address to the specific street name and house number in the MSAG, the ESN can be determined directly, and the call can be routed to the correct PSAP without further analysis. This technique has the potential to facilitate the deployment process and speed the nationwide roll-out of VoIP E9-1-1 service.

"The use of MSAG tables to determine proper call routing eliminates any routing errors that result from the lack of a national standard for GIS data," stated Dan Allen, Senior Vice President, Service Bureau Operations for TCS. "It simplifies the GIS maintenance requirements for both the PSAPs and TCS. This solution reflects TCS' continuing commitment to NENA i2 standards."
