MOUNTAIN VIEW, Calif., December 15, 2008 – Ditech Networks (Nasdaq: DITC), a leading provider of voice quality solutions to the world’s communications industry, announced today that its industry-leading voice processing platforms are now deployed by four major mobile operators in the Middle East region. Algerian carrier Djezzy, Pakistan’s Mobilink and Egypt’s Mobinil, some of the chief carriers in the area, are implementing Ditech’s Voice Quality Assurance (VQA) solution to provide their subscribers with superior mobile call quality without purchasing additional spectrum or network infrastructure, a common issue in this region. In developing markets such as the Middle East, new mobile service plans are being sold at an incredibly fast pace. Unfortunately, while promising for local economies, rapid increases in subscribership can have a negative impact on voice quality. In Ditech’s 2008 audit of over 630 million wireless calls worldwide, developing markets including the Middle East were plagued with poor voice quality on 59 percent of all calls. To quickly and cost-effectively accommodate new users, many carriers implement low bit-rate or half-rate codecs. In the presence of background noise or during peak calling periods, however, this tactic can seriously impact the call experience. Rapid-growth carriers like Djezzy and Mobinil have adopted Ditech’s VQA to help maximize their network capacity while maintaining voice quality for subscribers. Additionally, Ditech can offer mobile carriers voice quality solutions for 2G/TDM networks and the more advanced 3G, IP, LTE or WiMAX networks. This enables growing mobile carriers to provide superior voice quality over their 2G/TDM networks as well as next-generation networks. This eases migration for carriers by alleviating the need to deal with several different vendors for each technology. Ditech’s voice quality products allow them to operate hybrid networks, which frequently occurs when deploying new technologies or services throughout a network. “Carriers in the Middle East have numerous challenges to overcome in maintaining a differentiated service for their customers, namely, high subscriber growth, varying customer requirements, and diverse geographies,” said Karl Brown, VP of Marketing for Ditech Networks. “We are proud to play a key role in balancing the region’s mobile growth with providing superior voice quality to customers.” Ditech’s VQA solution is available on the Ditech’s Broadband Voice Processor (BVP) Flex and Packet Voice Processor (PVP) voice processing platforms, which provide a high-density, high-performance foundation for processing the large number of calls that traverse carrier networks. Both platforms are highly adaptable and easily reconfigured or upgraded while in service to meet operations needs or to accommodate new technologies carriers may want to deploy.
