Have received up to four (4) robospam phone calls per day to my sonic landline this week.
Most recent two today, email voicemail notification with my number elided:
>From 9100442343 at 910-044-2343 to ... on Thu Oct 29 14:23:54 2020 - 00:23 long.
>From U S BANK at 800-872-2657 to ... on Thu Oct 29 15:12:02 2020 - 00:21 long.
I think these originate offshore, from the generally extreme accents and speech patterns.
Sometimes the English language illiteracy is stunning.
Example: "If you wish to be your card verified, press one".
