The customer ordered a replacement 18D phone, I did previously tell him it could just be programming. I asked him to try Transfer 800 (would that apply to the iDCS?) and a few passwords. Unfortunately his former Samsung tech is no longer around. He can't see very well and isn't sure where the Transfer key is. He'll let me know when the phone arrives and we'll go from there. I've added phones and DLI cards to DCSs, would the MMCs be the same for the iDCS?
