Can I have a digital phone on with Fizz modem off, using same Internet connection?

My Fizz internet connection is recent and works fine but I keep power bar to modem off when I don't need Internet for computer. I want to replace my traditional telephone line with a digital line connected to Internet, using the splitter connected to the Internet cable coming into to the dwelling. Using the splitter, can the digital phone be active all the time, with modem off? I want to make sure before ordering digital line.

My other question (unrelated) is: Can I keep wifi broadcast off but use only ethernet with the Fizz modem (Model CODA-4680)?
