ELI5: Why can I have an international phone call with no lag, but news anchors and correspondents still have an awkward delay when communicating live internationally?

The telephone systems are connected by giant cables going across the ocean, spanning the continents. News and such have a lag because they use satellites, which has to send the signal into space and then back down. This takes (relatively) a lot longer.
