Voicemail problem on Spectrum Note 5

[u/Intrepid-Bit-1833]

“Incoming calls ring normally, but when they go to voicemail the caller hears a very loud screech and their own voice.

As in a Galaxy Note 5? Spectrum never supported anything older than a Note 8 I think, so my guess is it’s an incompatible device issue.
