How do I reveal a blocked caller ID from a call I already answered

[Haisley Mack-spraggins]

My boyfriend called me from a blocked number and tried telling me he just called me from his phone the way he normally does (which is not true there's no possible way). I answered it and spoke to him but I'm trying to find out what number he actually called me from because it's bothering me that he's lying about it. How do I reveal the caller ID without having to pay for a stupid app? Thank you for your input in advance
