i know that when an M3904 set is replaced the personal directory is lost; is there any way to save it or anything? my boss has an M3000 set that I basically know nothing about, but i do know he has some kind of directory on it and he puts some box in the handset cradle and saves it all. is there anything i can do with the M3904 as I am planning on replacing his M3000 with an M3904 (i know i can't migrate the M3000 directory to the M3904) but if i should ever have to replace the NEW M3904 can i retrieve all his entries somehow?
