Thanks for the help. The physical station extension is 121. I created a phantom device with ext. #132 & mailbox (associated - because it insisted).
I set a forwarding path for #132 to ring station #121, and then transfer to voicemail - which works so far, at least I think it does.
However, I can't change the message waiting indicator from #132 to #121 because, I'm assuming the extension is associated.
We have other non-associated voicemailboxes and it's no problem changing the message waiting indicator there.
On #132 (the phantom) the indicator says #132. Since I'm forwarding the calls to ring at #121, will the message waiting indicator follow?
If not, how can I accomplish this?
