Ahh ok.. I had never used it, was just checking it out for my cordless phone at home and was thinking of getting the BT250v headset so I could use the adapter and headset with my cell and home phone. Im not familar with a DECT phone is that a brand or a type of phone? I have a vtech cordless phone and a Audiovox 8910 cell. (sorry not trying to hijack your thread just got me curious if I should bother now)
