Steve Perich, also of Australia, pointed me to an older post on Telstra’s coprorate blog. It highlights the fact that earlier in the year they launched HDVoice capability across their mobile network. Given the size of their coverage area they claim to have the largest HDVoice footprint on the planet.
The blog post includes nice video that highlights not only the improvements to the audible frequency range, but also the fact that it’s possible to do a better of job of background noise suppression with the richer audio data provided by the HDVoice stream.

David Frankel’s ZipDX is the topic of an article over at Telephony Online. VUC regulars have been able to enjoy the benefits of the ZipDX wideband conference bridge for the past couple of months. The company has offered up their conference bridge to users who have the necessary phones to join the call in G.722-based wideband.

Just a brief reminder: Friday, April 3rd is the deadline for submissions from people wanting to speak at Jeff Pulver’s HD Communications Summit in NYC on May 21st. If you’re thinking of speaking you need to act quickly. If you’re thinking of just attending you can get tickets here.
Last Christmas my wife got me one of Plantronics .Audio 480 headsets. I’d seen this model of headset offered for a while, and since I’ve used noise reducing headphones for listening to music for many years, the idea of a similar approach to a VoIP headset was intriguing. She knew that I was searching out a wideband capable SIP soft phone and thought that a suitably capable headset might enhance my traveling arsenal.
My earlier experience with noise reducing headsets started with the venerable Sony MDR-NC10…which I simply loved, and had several sets over the years. I found them both comfortable to wear and very effective. The concept of soft rubber-tipped ear buds that form a noise blocking seal into the ear canal was simply brilliant.

I’ve been thinking a lot about headsets and headphones lately. This comes to be for a couple of reasons. Firstly, I left my favorite headset for listening to music in a coworkers car, and I don’t think I’m getting them back. Secondly, my favorite cell phone headset is very aged, and near death. Finally, I’ve been needing to upgrade the headset hardware that I use for telephony to better address my increasing use of wideband telephony. That has both desk-bound and portable aspects to be considered.
So I decided that I’d try a bunch of headsets of various sorts and see what I found the most appealing. This got started last December my wife bought me a Plantronics .Audio 480 headset as a gift. I’ve been using it quite a bit and I’m just about done with a written review of my experience using that device.

A short while ago I was informed that Counterpath had issued a new release of their Eyebeam soft phone for Windows. This release, v188.8.131.52 Build 51814 available from their support forum, was supposed to address the interoperability issues I encountered last fall when passing G.722 calls between Eyebeam and a Polycom hard phone.
I downloaded the program and took it with me on a business trip the following week. Upon initial installation I found that the program overwrote the version that I had been issued by ZipDX. I suppose this makes sense as both were in the v1.5 branch. However, the license key that ZipDX had provided would not enable the new release. I contacted Counterpath and they very quickly provided me a license key to enable the new release.
