I vaguely recall that G.729 and G.711 are both supported, but I need to double-check on G.722.

I feel like G.711 is widely used, so it can't be the answer. Maybe it's G.721?

I remember practicing a similar question, and I think G.722 was mentioned as a common codec.

I think G.721 is the one not supported, but I'm not entirely sure why it's considered obsolete.
