The Questionable Economics Of EHS Cables & Lifters
If you spend a lot of time on the phone then I believe that you need a proper headset. Many headsets require some form of interface hardware to connect to a desk phone. Many IP phones, like my Polycom Soundpoint IP series, require the use of an “Electronic Hook-Switch” (aka EHS) cable or a mechanical lifter.
A mechanical lifter is a Flintstone-like approach to hook switch control by purely mechanical means. It literally lifts the handset to take the phone off-hook, replacing it down again to hang up the call. To me this is essentially a kind of telephony steam punk.
Moving to 21st century methods, an EHS cable allows some aspect of the headset to control the hook state of the phone electrically. That is, it allows you to answer or hang up a call using switching that’s built into the headset. This may be true with both wired and wireless headsets.
To be blunt, lifters
In recent weeks there has been 
vs 
. Since that system is not IP-capable the “Select Services” menu is not shown on the handset.
This is a topic that seemingly will not go away, yet it’s not clear that there’s much uptake by customers. Going back two years, the first wave of “Smart HDTVs” were capable of running an embedded Skype application. With the addition of an optional camera/microphone module HDTVs from Samsung, Panasonic and others were able to provide 720p video calling from point-to-point.
This past week I’ve been getting to know Google’s Nexus 7. So far I’m liking it a lot. It’s interesting to see where I find it useful and where I still reach for my cell phone, netbook, laptop or desktop. How the Nexus7 changes my relationship with those devices is possibly one of the more interesting things about the tablet.
