FWIW, in my slow exodus from cable box to streaming, I just installed a
Magic Jack to accommodate my land line. As soon as I inputted where to port my number from (my provider - Spectrum) I got an email from Spectrum my monthly fee was going down approx. $40. So far (it's been about 1 week now) it's working just fine. In fact, I initiated an option to require callers to punch 1 more number in to get their call through and it has eliminated all spam/telemarketing calls. Caller gets a brief message and if they don't press whatever number is stated (it changes each call) it hangs up on them after "x" number of seconds. I tested the system out with my 96 year old Mom and she did just fine so if she can do it - anyone can.
I purchased directly from Magic Jack and the device arrived about a week later and purchase price included one year of service.
In total it was about $50........and annual renewal about $40.
The option to stop spam/telemarketing is worth paying almost any price, gotta say!
I don't really use my landline much - especially as I have gone into semi-retirement. But will keep it anyway to make calls out as I don't like using cell phones very much.
