*72 activates regular (immediate) call forwarding.  *73 deactivates.

I'm looking for Call Forward No Answer and Call Forward Busy Line.

I can tell you that most VZW customer service reps have never even heard of either feature let alone know the codes.

It appears the codes for Busy are:  *90 + 10D + Send to activate.  *900 + Send to deactivate.

*71 + 10D + Send activates BOTH features.  *73 deactivates both.

What I am missing is the codes for Call Forward No Answer by itself.
