I typically let them leave a voicemail and then call them back immediately if I need to. A big difference between spam callers and normal callers is that normal callers are extremely easy for you to contact back. Spammers want to call you, but don't want you to know who they are. It's actually a good security practice to not give out any personal information to people who call you. It's easy to spoof your doctor's office's phone number and start the conversation with "please validate the last 4 of your social so we know it's you". The only way for me to validate that it's actually my doctor's office is for them to give me some info about me that isn't public knowledge, which they won't do until I've already given them private info. Even if I did pick up when they answer, all I'd say is "Hey, I'm not comfortable giving out information to people who call me. I'm going to go look up your number and call you back, so I know you are who you say you are." The only time I ever have an issue with calling back is when my doctor needs to talk to me directly, but I recognize my doctor's voice. Someone could spoof my doctor's voice, but I heavily doubt that anyone would go through that much trouble to get my SSN or anything. I'm just not that interesting of a target.
