Until recently, we retained our land line because it’s a life-line service that is there whether or not you have power ( that is if you have a POTS only telephone instrument that doesn’t need house power to function). But AT&T wants to get rid of copper-based wireline phone service so they have continually reduced service and raised costs. So we elected to go with VOIP service which is cheaper, and if you have a battery backup on your modem, you have what is pretty close to lifeline service. The biggest problem with both services is “unwanted callers.” Now, 90% of our incoming calls are scam, telemarketer, etc calls and unlike a cellular phone, blocking is simply too difficult to use with either VOIP or wireline. As it is, my personal cell phone now has about 150 blocked caller numbers in my Contacts List.
So much for Do Not Call, another fraud brought to you by your “friends” at the FCC.
Would this work for you?
“The DPB works in Mexico, Canada and with all U.S. phone companies with standardized analog phone lines, DSL, Cable modems or VoIP (digital) phone service adapters, like FIOS, Vonage, Skype, Magic Jack, Ooma, Uverse and Cell Phone Gateways.”

We use it on our Verizon phone & it is a life saver - totally worth the money (& we have the model prior to this one). I’m not sure how VOIP works but you can check out the details.
