To see if there is something in your location that offers features
similar to Google Voice, you could search online on:

google voice alternative yourcity yourstate yourcountry

I just did a similar search which found articles reviewing several
alternative services. Alas, in the articles that I read, all the
alternatives cost money. Google Voice is free (and so is NoMoRobo other
than when using their Android app). Your own ISP might have voice
service with similar features but likely without the spam blacklist.
