hi, I have a Samsung series 2 sir-s4080r receiver. just bought it off ebay. the seller said it had not been use for a couple of year. I can't get it make a call to update the software. it has 6.3e-01-2-381 in it. when testing the phone line it will say dialing failed, phone is busy. I checked the line with a good phone, it has dial tone so the problem is not the phone line. the receiver does not give me the option to force it to make a call like my other Samsung receiver. please help if you can.
