I have my uncle’s recording of him singing me ‘Happy Birthday’ on my phone recorder which I’ve saved since June 2016 which apparently cannot be recorded other than via speaker phone to a recorder that makes a poor quality recording. So I seem to be unable to delete it if I want to hear it again so my message machine fills up continuously. My phone is ATT. Is there any way for me to record it to save his voice to some other media so I can replay it to hear him again?(both he and my dad,his brother passed away). Are there any home phone systems available that either record to a removeable chip, cassette, or whatever which can be saved other than an audio recording to another audio recorder which declines its quality significantly?

Use Your Own Voice Mail System. If you are using a phone that does not have visual voice mail, you can send a voice message directly to the voice mailbox of a phone number as long as the number is on the same cell phone network as your phone.. If you are unsure about whether or not you have visual voicemail, there is an easy way to check.
