I am having the same issue with no stutter tone or light. Called tech support 3 times. The first time they said my phone was the problem. I took it to a friends who has the same service and equipment and it worked fine there. The voicemail light turned on, no problem. I called again and let them know my results and they told me that they would resend the signal. Didn't work. I tried the online chat and the guy on the other end said he would resolve the issue. Still not fixed. I decided to buy a new phone to see if that was actually the isssue and called tech support for a third time. They resent the signal and reset all of my equipment and it still does not work.
Sorry for the inconvenience. I see that you have a current repair ticket opened to resolve this issue. I went ahead and refreshed the waiting indicator again. Someone will be in contact with you soon for resolution.
