Can you ID these telephone parts in trunk?

I've been having trouble with my COMAND cutting out momentarily at random times. By process of elimination, I believe it's the phone that is causing the trouble.
I removed both pieces in the picture from the MOST ring and everything seems to be working good. No dropouts.
The problem is I don't know what those two boxes are. i'm talking about the ones with the orange fiber optic cables.
Is one the phone and the other tele-aid? If so, which is which?
EDIT: How about these components? Different trunk. This one is mine.

It's mounted to the trunk floor and has a small electrical harness.
Forget that first pic. I found that one on the net since it was dark last night and i could not get a good picture.
Here is my actual trunk:

What is that thing on the right with the heat sink?

I bypassed them and everything works great.
I'm guessing one is he telephone and the other is the hands free module, but i am not sure.
