Vtech Answering Machine Not Working. Set up the answering machine that came with your vtech 5.8 phone. 1) make sure your answering system is plugged into a live telephone jack and power source.

With that being said, i have still not seen a response to my last question, which i will post again below. Make sure your system is set to record messages. How do you set up voicemail on a vtech 5.8 phone?
