A small breakthrough for this question, I have moved to a new office where union labor is required to do anything.
So in the end, the otherwise insanely expensive Beocom 5 telephone at $7 or 800 bucks or so was a bargain compared to hiring the union guys to run the wires.
It is nicely made, sounds pretty good, has good range, and a beautiful speaker phone charger base.
I am still learning my way around this device, but recently discovered that the speaker phone base draws its power from the handset, not the AC (or USB).
So in addition to the portabilitiy of the the handset, the speaker can also be moved around, cordlessly.
Dont know if any of you have tried the B&O phones recently, but for these or any other high quality cordless phones, can anyone suggest tricks / tips / tweaks / hacks to increase the range?
Thank you,
