Hello & Welcome to Just Answer,
Sorry to hear of the issue you are having with your phones.
May I ask:1) The Make & Model Number of the phone system you are working with?2) What phone service provider (phone company) you have for this phone line?3) Can you CONFIRM that you are trying to get into the service provider's Voice Mail system?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****
