Re: HD Voip?

"Telephones have remained unchanged for so long, most people have no idea what limitations they have lived with. This has begun to change with the recent rise of wideband technologies for the masses such as Skype. Now people are asking everywhere, "why does Skype sound so darn good?" The answer is that Skype is capturing double the spectrum of voice frequencies that are captured by standard telephones.

Standard PSTN, and the overwhelming majority of VoIP telecom codecs, capture at 8 kHz. Skype can capture at 16 kHz. The added fidelity in the high frequencies adds substantially to the realism of the reproduction, makes it possible to distinguish between otherwise difficult syllables of "s" "f" "c" "e" "d" and so on, and in an unmeasurable way, creates much more a sense of "being there" with the other person. The comparison is analagous to that of AM and FM broadcast fidelity."

We currently use several remote extensions, 1 in Canada. Using G.711u, the quality is better than PSTN.
