Microsoft continues to ride roughshod over people who have been users - at not inconsiderable expense - for YEARS. Skype itself is NOT free to use (even leaving aside my paid phone number) because it wastes hours and causes anxiety and frustration, each of which has a cost. Skype was never perfect but it had some degree of honesty before it was swallowed up by Microsoft.
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?
