What's the difference between Geoport Telecom Adapter I and II?

I want to use one as an answering machine because I'm getting a landline again. I'm tired of companies feeling like they can text me just because they have my phone number.

Thanks, I guess for my purpose it won't make a difference. I'm not using it as a modem.
