Received a call from 443-507-3238 on 4/15/2016 at 5:32pm EDT. Caller ID displayed "Hampstead MD". Did not answer and an automated message was left.

The automated message was mostly not in English but it contained some English words such as "internet" and "Philippines radio". The message ended with "If you do not wish to receive further updates, please press 1."

I have added this number to my Google Voice block list.
