Since switching from Optus ADSL to Optus NBN (HFC variant), the Message Waiting Indicator feature of Voicemail no longer works, even though I have selected Message Waiting Indicator in User Options.
So now, the only way to know if there is a message is to dial *96 and listen to the recorded Optus voice, whereas previously the stuttering dial tone (i.e., the Message Waiting Indicator) immediately alerted you there was a message without having to dial anything.
A call to Optus did not help. Optus passed the buck to the phone's manufacturer, Vtech, who said it's an Optus problem, with which I agree.
Other people on the forum seem to have had the same problem, but I haven't seen an answer that works for me yet.
I get a dial tone after pressing the Talk On button, as was the case with ADSL. Have tried turning MWI and Voicemail off and on again, but so far nothing has worked.
Could this be the issue? From our online help and support page: Voicemail Troubleshooting - Fixed Phone
No, someone else cannot have listened to/deleted messages.
The User Options Menu (Option 😎 is a little different to what you describe. Perhaps they've changed it recently. After pressing 8, you then press 3 to select your message notification type. The Voice informs you what is currently selected (Message Waiting Indicator in my case) and then gives you the option of changing it by pressing either 1 for Call Me or 3 for Message Waiting Indicator, at which point I again selected Message Waiting Indicator.
So it's still not working, I'm afraid.
Hmmm okay, not sure what it could be.
When you spoke to Optus, do you know what area it was? You may have better luck messaging the Technical Support team directly.
I'll notify our Help and Support team to check that the information on that troubleshooting page is still accurate. Thank you.
