you could do a leave mail in the LEAVE for phone A, with Phone B's vmbox as the destination.
OR if the destination changes frequently, do a generic GET from the phone a user, get the forward number paramenter, send it to $CP0, then string a leave mail to it with $CP0 as the destination. So whenever you go to leave mail, it will leave it for whatever is in the forward destination (must be internal though). I would probably put a test variable between the generic and leave mail to see if the extension is a valid system extension, and if not (like its an external number for some reason or just goofed) then it'll leave it for the phone A.
Now that I think about it, put in a generic and a test variable before any of this to see if the forward unconditional is actually enabled (0 or 1), then do whatever else.
