Hi friends, was happened to be in france for a month and happened to be on Orange network. Voice clarity Was exceptional and one of my colligue from zurich who was with me told that orange launched with ericsson HD voice BTS in france and clarity is exceptionally good. trust me it was far more then HDDDDDDDD and was consistently same across whom so ever i called. there was catch to it as i was carrying HD voice compatible Nokia N8, but still it was some thing i have never expericened in india not even on TATA DOCOMO NSN network. trust me signal was fluctuating but i never felt any difference. when would we get such clarity. Cheers to Ericsson!
