Depends on how many cells you want to use it for. There's space in DEE for Mobile, Mobile 2, Home and Home 2, so theoretically you could ring 4 external devices (by calling cell 3 & 4 Home and Home 2). With what you describe I think you'd need to break the chain of forwards maybe. I don't think a sys fwd for ext 100 to 101 will hit the DEE for 101. If that's the case use a CRA to break the fwd path: 100 fwd to CRA 200, maybe say "please wait while I try to locate someone for you" or just use no recording. CRA 200 would use TIME OUT in DIGIT TRANSLATION to send call to the phone or phantom 101.
