One option is to buy an Ooma ($80) and port your number to it ($40). The my.ooma.com site isn't responsive, but otherwise works fine on mobile.

I had never heard of them, but FWIW their "simplysafe competitor" says it comes with phone service, so that one-stop-shopping may interest this audience https://www.ooma.com/home-security/diy-security-system/#:~:t...

ed: however, unlike Google Voice it does not appear this service supports SMS/MMS so it's for sure not a one-to-one replacement :(

It _seems_ that Asterisk supports SMS, but from the wording I can't tell if they mean only in Europe or what https://docs.asterisk.org/Configuration/Applications/Short-M...
