Duofone TAD-311 answering machine

Not the kind of video I have uploaded in the past, but i finally got it working so I just had to show it off. This is a dual cassette answering machine. It was made in January 1988 in Korea. Also the phone is a Cortelco 2500 (VBA-20MD). The phone and the answering machine is hooked up to a Cisco SPA112 analog telephone adapter for use with VOIP as I don't have a normal landline anymore.
