Dan231,
I am sorry if it seemed like I was going off on you in particular, but so many people today had asked me about that button and kept calling it a Voice Mail button.
The issue is that we actually do provide a Voice Mail button on our Keymaps along with the standard Message Notification button. By the end of my day I am pulling my hair out as the steps I am providing them to do stuff didn't work and they all thought I didn't know what I was doing. In the end it was sorted out, but I had to go on site to do it. The bad part was one of our new trainers was calling it the Voice Mail button so I couldn't blame the customer for doing the same.
Sorry,
TE
