They called me I did not pick up the phone, they left no message. This is a number I do not know.

Just received a call from this number - I picked it up without thinking - they were speaking spanish so I just hung up the phone.  It sounded like a recording.

Received a call from this number, didn't answer. Went to voicemail and although a two second message was left, there was no speaking or sounds on the voice message. Called the number back and it greeted me with, "Welcome to Streaming Radio, please select a station 1 through 9". Once I did it just played music. Really strange, like a dial-in radio station of some sort, it wasn't just selecting your hold music. Hung up after five minutes because I wasn't transferred to anyone, it really was just music playing and I think it would have played indefinitely.
