left cann message, are you ...... if not hang up, wait 3 sec this is ..... as it goes on.... I erased the message. The message is the same that has come from different area codes and numbers day in day out.
Most likely RPM. robo calls spoofed phone numbers.
Short of changing my number big deal for me. I have changed my voice mail to sound like a disconected line or out of service. Though the people that know me know to wait and leave a message.
All numbers that come up with this type of message I assign to a special no ringtone and no message alert tone.

Canned message, are you "blah blah", if not hang up, otherwise wait for the message.   Debt collector clearly looking for someone.   I'm not home during the workweek so I get them every Saturday morning.

THIS NUMBER CALL ,S MY PHONE TWO AND THREE TIMES A DAY I GET A LONG MESSAGE THAT IS CRAZY

This is BYL Collection Agency
