Voysys worked with the 206 410 820 with FP2 and the Merlin plus R1 and R2. If you put the upgrade key in the side it would convert it to work with a 1030/3070 FP 4 or FP5.

You could put a Legend Processor in and use a laptop and 355AF cable to program or put an MLX card in too and use a MLX20L to program .

Regardless though, you have the wrong voice mail.

Anyway you look at it, you are probably going to want to call in an avaya guru that can program it up correctly.
