In the picture below, the one on the left (black) is in use, while the one on the right (red label) is one I found that I'd like to use in another location (to amplify incoming internet signal), so trying to figure out if they do the same exact thing.

It would appear to me the red one has more amplification? (15db?), but are they doing the same thing – amplifying the signal input?

I'm thrown off because the red one says it's for VOIP. I'd like to use it for the same purpose of increasing cable internet signal strength coming into the house, but didn't know if they're functionally doing the same exact thing. Is the VOIP output on the red one the same thing as a normal output?
