Satellite internet cannot support VOIP, because of excessive latency.
It takes over 600mS for the signal to get through (considering the
distance to synchronous orbit).

I think you can call people but not talk to them. You might hear them
complaining about that.

I considered getting VOIP, but was worried about quality and
reliability. The POTS system is very reliable. Cable has more outages.
Instead of the highly reliable phone line, you get a not-so-reliable
ISP and a less-than-reliable VOIP provider.

Uh, mebbe not 'residential grade' internet-over-sat, but commercial grade
internet over sat supports it okay. I know, we use it at several sites. The
problems is has aren't due to the sat connection per se, but just due to too
many hops. Google 'Tachyon' for specifics.

Yes, an RJ11 plug will fit in an RJ45 socket. The center pair of an
RJ45 jack is reserved for telephone, even though it's seldom used that
way. It's up to you to wire it up.

I've often heard that it's not a good idea to have telephone and
ethernet in the same cable. That's why some people install TWO cat5
cables everywhere. The wire assignments (different pins for ethernet
and phone) help prevent damage caused by plugging something in wrong.
