I have a cordless landline with a ph # I’ve had 20+ yrs. In its time it was a very nice unit - compact, built-in answering machine, with extendable base units. At this point I guess I have it just to have it as it is still associated as my “home” phone with some of my long standing accounts. It is bundled with my Verizon FiOS package and I think my bundled cost is cheaper with the LL included. Back in the day it was my primary # with my early cellphones serving as emergency backup. Eventually flip phones became smart and I set my LL to forward all calls to my mobile. Hard to identify any particular benefit my old LL provides but I don’t see any real downside to holding on to it. Call it nostalgia maybe
