Hi Oliver,

I'm am quite certain I read a bunch of material about using phones + 
bluetooth for presence detection. However, any particular reason you are 
trying to use Asterisk in this combination? I am quite sure there is 
software out there (I think for Windows and Linux) for bluetooth 
presence detection. What advantage would Asterisk bring for this scenario?

If you are trying to integrate it with Asterisk so that the phone 
switches to voicemail etc. - then maybe it is worth giving those 
usb-over-ethernet solutions a shot. After all, you are not trying to do 
voice over bluetooth - just detecting the mobile. I'm afraid I don't 
have any experience with that though. And I wonder what would the 
security implications be of having all those usb ports virtually 
connected to the server, but physically located away from the server?
