I'm using an Obi100 with Google voicemail. I have a Vtech DS6511 attached. Everything seems to work fine except the voicemail indicator on the phone. Regardless of whether I have voicemail or not, the phone's voicemail icon is "lit", it says "voicemail" on the screen, and when I call out I get a dial tone stutter.
If I actually have voicemail, I am able to access it fine. Otherwise, I get a recording that I have no voicemail even when the phone thinks I do.
Do I have something set wrong on the Obi100?
Other than this issue I think it is an impressive device.
