Since our house has good quality internet via our cable TV provider, we switched our brick & mortar house phone service to NetTalk, a carbon copy of MagicJack. We pay around $40 a year for unlimited nation wide phone service. It works extremely well with our Gigaset 300 wireless house phones which has an answering machine. Our original Siemens wireless house phone system was not compatible with either MagicJack or NetTalk. We bought a 1st replacement wireless house system which also had issues. The 2nd attempt, the Gigaset 300 system works perfect. And it works well with the old wired phones sprinkled around the house.
I wanted to drop the house phone altogether and reply exclusively on our cell phones, but my wife Irene wanted to keep the house phone so this was a great compromise. I thank her for doing all the research trying the two different service providers and 3 different house phone systems to come up with a good working, very affordable home phone service. I am glad Irene found a cheap means of keeping the house phone, especially now that I am retired.
