Russia's MegaFon has deploy HD voice on its GSM and UMTS networks in Moscow and Sochi.
Nokia Siemens Networks was responsible for the HD voice implementation. Nokia Siemens Networks' HD voice is based on Adaptive Multi-Rate Wide Band technology* (AMR-WB) that provides service continuation between GSM and UMTS networks, and supports Megafon's network.
"The main advantage of HD Voice communication is the impression of a live, emotional talk between people. HD Voice users can forget about ‘robotic voice': they will hear their relatives, loved ones, friends or business partners exactly like in a live talk – with all nuances, hues and tones of speech," said Igor Akulinin, first deputy director of MegaFon-Moscow. "For MegaFon the HD Voice Project is another example of implementing innovative services which open up new, previously unavailable opportunities for our subscribers."http://www.nsn.com
