The closest you can get now is by configuring the users primary line they first get calls on to have a busy trigger of 1, then forward busy / forward no answer to a second, third line on their phone.
This way if they are on a call on their main line, with busy trigger 1 it will roll to second line and ring there, and any other lines then roll to VM and the forward reason will be busy since the primary line busy trigger was 1 and they were on a call.
But you need to be on call manager 4.x for busy trigger setting on DNs.
