I stated with the original Magic Jack that connected thru my computer. It was good but sound was not quite perfect.
After a few years I upgraded to Magic Jack +, and the sound quality was as good as any land line. The cost was almost negligible. Unbelievably cheap. Later my Internet bundle offered a cheap VoIP phone if I bundled TV, Internet and phone.
I have kept the internet bundle and phone but use the Magic Jack + as an additional line and also to operate my FAX machine, which also works perfectly. Can't say enough good about Magic Jack.
