I got a call from this number.  The caller i.d. says Denver Co. They left a voicemail on my phone.  It was dead air.  They didn't say anything.

I keep receiving annoying calls from this number about 3-4 times a week. According to the caller he is calling from some Pretrial Intervention and if they don't hear from me or my attorney, I waive my rights to have an attorney and they will go on with the case and at the end he says handle myself accordingly. Why can't these calls be stopped? In this day and time I feel that when these type of calls are reported, there should be a program that can trace these calls. Tired of these scams.
