"Hello" you say
and just and friendly I'd speak back.
Yet it's a lie, I only quote
that welcoming into my throat.
Surely, you think, they're just for show,
those fangs you see both high and low
and though my heart's as black as night
you needn't worry - I won't bite.
Rather I'm much like a fairy tale troll
swallowing anything that comes to me whole.
My skin is thicker than any bruit,
yet I haven't life and alone I'm mute.
What am I?

An Echo

Stalagmites/tites

Taking the other hints into account:
You are a cave/ a cave mouth
This looks to me like :
A Telephone
"Hello" you say and just and friendly I'd speak back. Yet it's a lie, I only quote that welcoming into my throat.
We say "Hello" and the other end replies "hello" as well. It's a lie because the phone doesn't speak it only quotes the person who talks to its throat(Receiver.)
Surely, you think, they're just for show, those fangs you see both high and low and though my heart's as black as night you needn't worry - I won't bite.
The fangs are the buttons on the receiver end as well as the keypad. The heart is black might be a reference to its battery or the chip sets, and yes the phone doesn't bite.

Telephones can seem ugly trolls or they can be used for trolling. Bruit means spreading a rumor widely. Thicker skin can be a reference to "phones can spread rumors very rapidly."
Alone, its always mute. it only comes to life when someone calls.
What am I?
a Telephone.
You are...
a cave.
"Hello" you say
and just and friendly I'd speak back.
You talk into the mouth and it echoes back.
Surely, you think, they're just for show,
those fangs you see both high and low
and though my heart's as black as night
you needn't worry - I won't bite.
Stalactites and stalagmites are the fangs.

swallowing anything that comes to me whole.
As you walk in you are swallowed whole.
My skin is thicker than any bruit,
The whole earth is the thick skin.
yet I haven't life and alone I'm mute.
No sound unless someone or something makes a sound inside.

What comes to mind is
A fun-house ride. The only problem is, it seems too literal.
"Hello" you say and just and friendly I'd speak back. Yet it's a lie, I only quote that welcoming into my throat.
Lots of people when they go into these rides yell "hello!" to hear the echo, I suppose. I've never really understood this. The ride usually has some sort of greeting that plays over and over in a loop, so it's a quote rather than a real welcome.
Surely, you think, they're just for show, those fangs you see both high and low and though my heart's as black as night you needn't worry - I won't bite.
The entrance is often a mouth. The ride is usually dark inside and, though it may look scary, is actually safe.
Rather I'm much like a fairy tale troll swallowing anything that comes to me whole. My skin is thicker than any bruit, yet I haven't life and alone I'm mute.
The cars or boats of the ride go into the mouth hole. The sides are plywood and canvas - thicker than any "brute"'s hide. It is operated by the guy at the switches and it goes dead whenever the power is turned off.
I think you're:
Siri
"Hello" you say
and just and friendly I'd speak back.
Speak to Siri and she (or he) will reply
Yet it's a lie, I only quote
that welcoming into my throat.
All the answers are pre-programmed
Surely, you think, they're just for show,
those fangs you see both high and low
Those sound wave when you speak that looks like fangs
and though my heart's as black as night you needn't worry - I won't bite.
The phone itself
Rather I'm much like a fairy tale troll
swallowing anything that comes to me whole.
You can tell / ask Siri about anything
My skin is thicker than any bruit, yet I haven't life and alone I'm mute.
Phone case, and Siri is only a program and do not speak if not activated
What am I?
Siri
Definitely
A cave: A dead, thick-skinned object with echoes, a black heart of darkness, non biting fangs of stalactites and stalagmites
