So this question and topic was brough up in the past, and i’m sure many times, so in the case people bring their own hardware (BYOH) and save on electro waste and self managed there network. as many other providers like Swisscom offer it, actually since many years!
Well documented here: https://www.swisscom.ch/en/residential/help/fixed-network/sip-credentials.html?TR
They basically expose the provision SIP in RES and SME products, for business and enterprise you could always get it, shared vi SMS. I’ve had that for years.
So how can we build some critical mass for this request? Who can we talk to and how can it be done, (because I know technically it’s completely possible)
