Who called from 5082221031

I got 2 calls from this number early this morning both an hour apart...voicemail said it was a collect call from an inmate...not sure what this is about...very strange!!

Call me like 8 times. I dont know anyone in jail.

Called 5 times starting very early in the morning...woke me up!!!!  Looking for money from jail.  I don't know anyone in jail.

This is a legitimate number.  It's a collect call service from inmates at Worcester City Jail.  I thought it was a scam at first, and then found out someone I knew had been in the jail and had tried to call me.
