@CenturyAvocado No it isn’t - the #PSTN (Public Switched Telephone Network) is the network as a whole. #POTS is the method of accessing that network that uses copper.
Calling it the #PSTNSwitchOff is like calling a #dialup shutdown the “Internet Switchoff”.
The network itself isn’t going - just a common way people have used to access it.
"Stop ISPs enforcing use of their own router for VoIP phone lines
With the switch off of PSTN telephone lines in 2025, many ISPs have started to provide VoIP phone lines with their internet supplies. This is great, however, use of these VoIP phone systems is often restricted to only work when used via the ISPs provider router/modem.
The government should enforce ISPs to provide VoIP information so a user, if they wish, can source their own VoIP to analog telephone adaptor allowing them to use a custom third-party router if they desire. Failure to do this creates a vendor lock-in problem, and means switching providers can be immensely difficult and ultimately lead to people sticking with one provider in the fear they will lose their telephone number if they do switch."
