Receive a few calls every week from this number to my cell phone.  No CID with the call just the phone number. I have never had the chance to answer the call and they do not leave a message.  I called the number back and got a recording saying the number has been disconnected.  I Googled the number and it shows that it's a number for an adult escort service in Baltimore.  Not sure what that is all about, maybe it's a caller spoofing a phone number.
