YES, if you have high speed cable modem (not DSL)

I tried MagicJack, but volume was low, and noisy ..

ooma works much better (connects between cable modem and router)

I bought the "old" system (not Teleo).. NO monthly fees....(basic)

Hub and Scout was on "sale" for $168 after Bing CashBack.

thanks for the info Regus! So, teleo is the newest and hub & scout are older versions.It's really hard to discern the info from their site. Time to order!
