They claimed to be with National Firefighters Association, saying they lost a lot of firefighters this year and wanted me to send them money in the mail. I told them I only support local volunteer firefighter stations. They hung up. Clear indication they were just scamming. Never give money to anyone calling over a phone. Not even to save kids in Africa facing Ebola. Doesn't matter who or what they claim to be. If they are calling you asking for money, it is a scam.
