Give me Presence- Now!

I was recently given a rather swish IP desktop phone gratis by a supplier to put on my desk at work. Here is a tiny picture of it...

Why did they give me a phone for nothing? Smart Marketing. I'd work out how to get the best out of it and the Green-eyed monster effect would hopefully result in Bosses coveting it. To prevent the bosses coveting it too much to the extent that it would transport itself up to Mahogany Row, it was given to me as a thank-you for working proactively with them on recent installs.

So when I retire, or move on, I can lay claim to the phone as my own and lug in my old one in its place. The only trouble is that I'd need a £100k phone system at home to make it work and by then they will probably be worth 50p on eBay!

Also by then, hopefully they will have gotten the bugs out of it. The old one was a single keypress to activate redirection of my calls to voicemail if I was stepping away from my desk for some reason. The new one takes six key presses to activate it and the feature doesn't actually work anyway...

What i want is the phone to be able to react to my presence according to pre-defined rules. How will it know I'm there? To be automatic, it would need to use RFID on something I had on me, maybe a phone pairing ID card in my wallet or perhaps on my Security pass that I wear on a lanyard all day.

Of course, I don't just want that to apply to my phone- I want my PC to work the same way as well so that it automatically locks when I step away and unlocks again when I return, updating my messaging presence accordingly. It doesn't negate the need for a second authentication factor
but it will make office life so much easier and make communicating much more effective.

Come on Networks Industry, I;m waiting and I'll buy one...
