Just got one from this number too,
No message.

Now blocked

I just had the number call too. Then my voicemail notification came on. The message sounded like wind and then a beep noice then it ended. My caller idea says its a Pacific, MO number.

I didnt answer  and No message left...

This number just called. came up as a Pacific MO number. I didnt answer and they left a 5 second voicemail not saying anything.

keep calling and when I listen to the voicemail it is just a hang up call- I call them back and the recording says they are researchreward.net
