Video calling is "easier" in that the p2p option is workable for some variant of "Works".
It is much much harder because you can't do the "cache everything on the edge" solution. If storage was infinitely cheap and small, Netflix could run their entire business by sending a USB stick with every single movie/tv show they have on it encrypted to you, and everything would play locally. This is basically what they do with their edge servers/CDNs.
You can't do that with video calls, because the video/audio didn't exist 1 millisecond ago.
