I’d like to add these guys to my series on Making Use of HDVoice Right Now, but a cursory look at their service offering reveals that their free accounts don’t have access to G.722 based services. You must be on a paid account to get into the trial. To date everything in that series has been possible with free accounts from the likes of Skype, OnSIP, Gizmo5, SIPGate and IdeaSIP.
