On Tuesday in London I chaired a technical workshop focussing on High Definition Voice. The event, run by the Internet Telephony Service Providers Association (ITSPA), was generously sponsored by Cisco and Broadsoft and who also provided some working demos together with ITSPA member YeaLink.
Around 40 or so people from the industry held a very informative discussion. Clearly the vendor community is getting there with support for HD voice. The service provider world has yet to catch up really and in particular the connections to the PSTN are not by and large there yet.
