The most frustrating thing about FaceTime is it sometimes appears to significantly duck audio in order to avoid echoes. I can't predict on which devices it will happen, but it often does when I call my parents and it absolutely destroys the conversation. If they're telling me something and I make the slightest "uhuh" acknowledgment sound, their mic input gets effectively muted for a second or so and I miss what they say.
