Yes, STUTTER TONE works

The VMWI led on my UNIDEN phone works great.

The GS button will flash a green light too.

UNIDEN phones with answering machine built-in ignore the VMWI sign.
Does yours have its own answering machine built-in?

EDIT: I never had the second instance of my same line, using a ZyXEL ATA, work for STUTTER TONE or VMWI. But that is not a concern for me, and only GS are officially supported.
