We still use our PSTN phone with No Mobile signal in our village and classed as Vulnerable and we get power cuts.
I know the PSTN system is supposed to be turn off January 2027.
I also know I could port my number that we have had for 42 years to a VOIP provider (but why should I

).
My setup at the moment =
BT paid Phone line ( calls go through an ISP )
ADSL2 over the BT line with a separate ISP with who we get 1000 minutes of free calls a month, then if they are used up we pay any other calls through them Not BT..
Still have large amount of email addresses with them.
FTTP (over BT Openreach) with a small ISP.
We have our Own domain for emails etc.
I intend to wait and see what BT will do about my set up and I will not have another BT broadband account to work the Digital VOIP phones (Unless it's free ).
Any Idea's what could happen. ?Anyone else in similar situation. ?
