Just setting up a home office and have tried reading up on this with little joy. from what I (kind of) understand. This unit will plug in to any telephone and provide you with a) better sound quality and b) the ability to plug a plantronics "wired" headset in to it?
Ideally I am after something to convert my landline in to something I can use my Blue Tooth headset with, so perhaps I am wide of the mark here.
If it is only wired headsets this works with, presumably you don't have one for sale as otherwise you would have listed it, but thought had better ask.
Look forward to hearing back,
All the best,
Nathan
