My cordless phone will either not place a call or will cut the call short saying no contact with base. It comes and goes repeatedly which forces me to use my cell phone instead. I have checked all connections and power is up. I have 5 handsets and no matter which one I use they all act the same from my office. I have Cox internet thoughout the house so what is the haps? Any other part of the house the cordless phones work fine but when I put it in my office it cuts out. My cordless phone in bedroom (just across from office) I have no problems with at all.
