Airtel Partners with Dialogic for Bandwidth Optimization for African Operations

Monday, August 29, 2011

Dialogic I-Gate Media Gateways have been deployed on microwave and satellite portions of Airtel’s African GSM network. This deployment optimizes voice bandwidth capacity, resulting in significant CAPEX and OPEX savings for Airtel, as well as high quality voice services for Airtel’s customers.

Milpitas, CA - August 29, 2011 - Dialogic Inc. (NASDAQ: DLGC), a leading provider of communications technologies that power advanced networks, today announced that the Dialogic® I-Gate® 4000 EDGE Media Gateway and I-Gate® 4000 PRO Media Gateway have been deployed on microwave and satellite portions of Airtel's African GSM network. This optimization solution increases voice bandwidth capacity on the same network by eightfold, resulting in significant CAPEX and OPEX savings, while maintaining high quality voice services.

Airtel is very pleased with the performance of Dialogic's I-Gate 4000 Media Gateways and is also looking ahead, since as Airtel continues to invest in its network and increase its subscriber base, it is critical to have a voice optimization solution that is reliable, cost-effective and able to maintain exceptional voice quality.

"We are excited to provide Airtel with a voice optimization solution that meets its operational needs," said Kevin Cook, executive vice president of worldwide field operations at Dialogic. "3G networks are beginning to evolve in Africa, and the demand for mobile data will in turn increase bandwidth requirements on service provider networks. In addition to our I-Gate Media Gateways, Dialogic offers an even more advanced mobile backhaul optimization solution through our Dialogic® I-Gate® 4000 Session Bandwidth Optimizer Mobile Backhaul (SBO-MB) product, which has been demonstrated in trials to as much as double existing bandwidth for voice and data traffic across existing mobile backhaul networks."
