I've got a need for a gadget, and I'm thinking that there's got to be something like it available somewhere, but I can't find it. I work in a semi-office type environment, and we have one desk phone for the department. It works for most needs -- people go to the phone to make or answer a call -- but there are times when we've got a tech support call for a piece of equipment, and we'd like to be in front of that machine and on the phone at the same time. But the one-desk-phone-for-everybody thing majorly hampers that.
So what I'm looking for is a way to extend the phone that doesn't involve 100 feet of phone cable strung through the office or spending several hundred dollars on a wireless multi-line phone unit. Is there something that will create a wireless audio link between a phone base and the handset, basically replacing the curly 4-conductor cable? It seems like it'd be a simple enough thing to send two channels of audio through the air, but search as I may, I'm coming up empty. Anybody seen such a thing?
I can't believe I'd be the only one wanting something like this. Or is there an easier solution to my problem?
