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?
To set up a personal voicemail greeting on a Galaxy S10, open its Phone app and call your voicemail, then tap "3" to enter the settings.

Nobody wants to listen to a long-winded voicemail. Keep your greeting short, simple, and concise. A voicemail message should pique a client’s interest and leave them looking forward to your call. Stick to the basics, explaining your company name, hours of operation, and when to expect a callback.
When you have new voicemail, the Phone tab in the Skype for Business main window displays the number of your messages. See Contact Card opens the caller's contact card, which lists their phone number, email address, office location, and so on. Open Item in Outlook provides more information about the call.
