Using により to specify method?

Question

Here are two examples: > [電話]{でんわ}による[通報]{つうほう} // Fine > 電話により通報する // Okay? I feel like using `により` is strange in my second example, but I'm not sure. Is the second example perfectly fine grammatically? I feel like `電話で通報` or `電話から通報` would be better.

Answer 1

Yes, but won't be so in all cases because NI YORI is a formal/written form of NI YOTTE. As those are more expansive than NI YORU, you need to be careful.
