Nothing gets my blood pressure rising like someone passing off bad or misleading information as the real deal. This afternoon I followed a link in someones Twitter stream over to VOIP School where there was a post about HDVoice dating back to mid-June. Go ahead and read it, that way you might come to understand my exasperation.
Not long ago telecom writer and blogger Doug Mohney issued forth a Tweet asking:
“Anyone out there using HD calling (G.722) on a daily basis?”
I’ve not met Doug, although I sat a few seats down from him much of the day at last month’s HD Communications Summit. I’ve read his work at various places including FierceVoIP. Doug truly knows telecom.
What his tweet brought to mind is the simple fact that many people might be interested in making use of wideband voice, but not know where to start. I use wideband voice, in one form or another, literally every day. If you’re a technical sort it’s not that difficult. For the non-technical it can be a minefield. So I thought I should offer some suggestions based upon my own SOHO experience.
Telephony Online has today's release about Optimum Lightpath offering wideband business class voice service. Doug Mohney, aka Doug On IP Comm, has a bit about these events as well. His headline is "HD Communications – Cablevision fired the first business HD…
One common misconception that keeps coming up is the assertion that the higher quality audio available through the use of wideband telephony (aka HDVoice) requires more bandwidth on the network. This is simply not true.
The terminology gets confusing for some folks. On the one hand we’re talking about frequency response of the audio channel being much greater, 50 Hz to >7 KHz for most wideband codecs, as compared to 300 Hz to 3.4KHz for the reference standard G.711. All that extra information has to go somewhere, right?
Things are starting to ramp up prior to next weeks HDComms Conference in NYC. Audio Codes is presenting a webinar entitled "HD VoIP: The Next Sound Barrier" on the topic this coming Thursday, May 14th at 9am EDT. This presentation…
I don’t generally hang around in public VoIP forums but I do monitor several using Google Reader. So it was that Tuesday evening I found a new thread about “HDVoice” at the VoIP Tech Chat forum on BroadbandReports.com. Someone had posted a question about the significance of HDVoice and a few braves souls were weighing in with their take on the matter.
There was some good information, but a little confusion about data rates and the possible use of ATAs with wideband voice. It looked like the start of a good conversation on the subject, in a potentially interesting crowd. I thought I’d offer my two cents…which kind of unexpectedly turned into more like half a dollar.
