It looks similar to something else I use. We got this box and it plugs into one of the wall jacks and then phones work in the home.
In your case, why not do that? Plug a cable from that Home Connect to your home phone wiring and then use your dialup modem?
Did you try?

We live in dialup land and would like to hook up our dialup service to the cellular service Verizon Home connect. Is there a way?
