The fun project aspect is the only reason I'm doing it really. Since switching to full fibre and finding that we no longer
need a phone package just to get Internet my brain lit up with the possibilities of cheap/free SIP and FreePBX, most notably around Lenny seeing as 99.9% of all calls we ever got to our home phone before we unplugged it was spam.

My ultimate not-very-interesting-in-reality goal is to whitelist a few known numbers to directly ring a normal phone, so that we can get hold of the kids when they're home alone, and shunt everything else straight to Lenny. Maybe with a secret code to escape him and get through to the real phone...
I got the "shunt everything to Lenny" bit working last night, so stage 1 is complete.
