I would like to disable/eliminate voicemail on my account so that my home answering machine picks up when I don't answer.

My phone number does not have access to Advanced Call Forwarding, so I am unable to change the number of rings.  I am old, so I can't always get to the phone before 5 rings and don't know how to access Xfinity Voicemail (my son is helping me with this message).

We found instructions mentioning sending a direct message, but there is no Direct Message icon on the page.

Please advise.
