Humans can only hear beetle-steps with amplification, unless the beetles are walking on a surface that crunches or rustles, such as dried leaves. Other animals (such as birds) with more sensitive hearing can usually hear the beetles foot steps.

Yes you can hear it. I was on a phone with someone that got hit in a hit and run from the rear and could hear a boom sound.===========================You would hear it UNLESS the cell-phone was the point of first impact,which is very unlikely.
Snakes cannot hear. However they can sense ground vibrations.
I'm not exactly sure but my guess would be that directly contacting someone would mean communicating with someone (or something) while the other person can hear or see you, or when you are there in person. Indirectly contacting someone would mean you would cause someone (or something) to contact someone (or something.)
