The VUC call featuring LifeSize, originally set for February 4th, has been rescheduled to February 25th at 1PM EST. That makes it part two of a VUC double-header that begins with Safi Systems at the usual time. All of the…
Randy Resnick (a.k.a. Zeeek, or more recently Dulo Par) the founder of the VoIP Users Conference, has a guest post over at HDVoice News called, “An “ear opener” to HD voice in conferencing.” Randy details the advantages of wideband voice for large public conference calls. He should know, having produced thousands of hours of podcast based upon such calls over the past few years.
When I heard that Randulo had arranged to have Gizmo5's Michael Robertson as last weeks VUC guest I just knew that I had to find a way to free up an hour and be on that call. Were you there?…
As expected the VUC call on Nov 7 about wideband VoIP proved very interesting. It was well attended with a dozen participants on the ZipDX wideband bridge and another twenty on the Talkshoe narrowband conference bridge. Our guest, David Frankel of ZipDX, did a good job of introducing wideband telephony, it’s advantages and some of the issues surrounding its implementation.
We recorded the call in several places so that we have both wideband and narrowband recordings available for comparison after the fact. History has shown that many people download the conference recordings, even many months after the original conference date. It’s evidence of “the long tail” phenomenon that we hear about so often.
However, some people are very visual so I thought I’d bolster the archive recordings by doing some simple visual analysis of the spectral energy distribution in each type of call. Happily, Cool Edit Pro (now Adobe Audition) makes it really simple to generate both waveform and spectral views of an audio clip.
A few weeks ago I bought a couple of Polycom IP650 SIP phones from Michael White at E4 Strategies. This company was recommended by Karl Fife, a regular on the weekly Voip User Conference.
e4 had some IP650s listed as “open box” and offered at a discount so I ordered a pair. A day later Michael responded that in fact the open box units were sold out, but he’d honor the price for my small order. That’s great, I thought. And they were delivered quickly, too. All in all an excellent purchase experience.
Kerry Garrison of Fonality appeared on The Voip Users Conference Friday December 21 to address the recent fervor over the matter of Trixbox implementing a script to automatically send system details back to Fonality. Kerry did a good job in…
