Hi, so I have 2 verizon cell phones in my home and the cell signal here is abysmal. Even though I'm within spitting distance of downtown Chicago, my cell signal at home is frequently 3g and 1 bar if i'm lucky, on either phone (samsung galaxy s6 and s7). i would like to do one of the following, but i have no clue about either right now 1. use our cell phones to make calls over wifi. i have great internet and strong wifi throughout the house so if i can configure my phones to use wifi to make calls, that would be great. 2. i do not want to pay my isp for voip but i think there are devices out there that i can add to my network that would provide voip type service. i do not mind purchasing a device to install on the network, and then purchasing a "regular" phone to connect through that other device in order to get phone service. any recommendations would be greatly appreciated. i am tired of having to make calls and have conversations next to my patio doors at either end of the house lol. thanks for any and all feedback!
