It appears that HDVoice is making considerable strides in the UK. Orange recently launched HDVoice calling for their mobile users, offering a selection of three HD-capable (AMR-WB) handsets from Nokia. The HDVoice section of their web site highlights the difference in call quality nicely.
Further, their new service caught the attention of the BBC, who offers yet another nice online example of HD vs PSTN call quality.
Step ahead just one week and we find that XConnect has announced their HD Voice Exchange peering effort is now available globally. In addition, they have joined in partnership with Polycom, Broadsoft and Dialogic in a new effort to promote the increased adoption of HDVoice by UK-based ITSPs.
