Male caller claims to be from IMC calling on behalf of NRA because "it is a critical time". I told him the person he was asking for was not at home so he said "no problem, I'll call back later" and hung up. Most probably some type of scam as this number has called numerous times and never leaves a message. Sometimes the caller ID has IMC on it along with the phone number and sometimes not.
