I had mine much longer than I probably would have because for a while I had a “triple play” deal from the cable company. When I called them to see about taking the phone off because I mainly used my cell phone, they played the card that if I removed one of the triple play items, I wouldn’t be saving as much and I would actually end up paying more. At that point, my landline number became the number that I gave to people if I had to provide a phone number, but I really didn’t care if I ever talked to them. And that’s really where most of the robocalls and telemarketing calls went, was to my landline.
Eventually I got disgusted with how high my cable bill was and decided to cut the cord and just keep my internet. At that point my landline was gone, but it’s fine. At least my cell phone doesn’t have a limit on the number of phone calls you can block, which my landline did.
