Audacity Noob - Trying to add recorded phone call to current track

SO, I am by far a noob to any type of production, etc… We are working on a podcast and are incorporating interviews into the podcast. I am trying to add a recorded call to a section of the podcast, but am unsure how to make this happen. I am using Audacity 2.3.3 with Windows 10… Any help for this noob would be greatly appreciated!
