New Gear: ClearOne Chat 160

At lasts years visit to Astricon it became clear that  it would be good to “tool up” for having conference calls at remote locations. As I described previously, the ClearOne Chat 50 USB speakerphone that I had brought along was not really adequate to the task of a conference call with a number of people scattered around a hotel room.

I can’t fault the device as it, like most USB attached speakerphones, are intended as personal audio devices, to be used by an individual at a desk. It’s microphone pickup pattern describes a 120 degree arc across the front of the device. That means that fully two thirds of the room are off-mic and won’t be heard very well.

Answering A Few Questions About HDVoice

Some time ago over in the VOIP Forum at Broadband Reports there was an interesting thread about wideband telephony and it’s relationship to common ITSPs. The person who started the thread was surprised to find that they could not pass wideband audio between two accounts on the same SIP-based ITSP.

Holy cow, I just tried to pass G722 and Speex wideband through voip.ms and it choked !! I can’t believe it, I thought they were supposed to be one of the more competent providers.

This person’s presumption was that if the call is between accounts at the same service provider it doesn’t traverse a media gateway, and so should support any desired codec. While the logic was basically sound, clearly this wasn’t the case as the person soon found out.

A Curious Pair: Skype & Traditional Broadcasters

As Skype has become more and more popular various other parties have tried to ride on their coat-tails, including old media companies like TV stations & broadcast networks. I know of at least one TV station that was clandestinely using Skype over broadband to “phone in” breaking news events. The station in question even went so far as to promote the fact that they were using Skype. They did so without prior permission from Skype, and were eventually asked to stop doing so by Skype’s lawyers.

TV stations have been doing “Live Remotes” for decades. Most often this involved using a vehicle equipped with microwave relay gear to send the video feed back to the station in real-time. Much effort goes into ensuring that the video signal looks good when it finally hits air. Larger TV stations or more important projects might merit the use of satellite transponder time to get the video feed back to the station via a satellite link, at considerable expense.

Wired Headset Happiness: The Return Of ETY.COM

Despite the fact that I have a couple of very good wireless headsets I still find that a wired headset can be handy. This is true both in the office and on the road. While lately I’ve been traveling with a Plantronics Voyager Pro UC cordless headset I also keep an Etymotic ETY.COM wired headset in a my laptop bag.

I’ve mentioned the Etymotic ETY.COM wired headset previously. It remains my favorite wired headset for mobile use. It sounds great and has a boom that reaches around to the corner of my mouth, which is ideal for use in a noisy environment.

However, since I changed cell phones back in November 2009 I’ve not been able to use the ETY.COM with my cell phones. Whereas the Blackberry Pearl has a four conductor 2.5mm jack for the wired headset, the newer Blackberry Bold2 (9700) has a larger 3.5 mm headset jack. The ETY.COM doesn’t fit the 9700 without an adapter.
