As the PSTN lines are going to be phased out in 2025 , is there something else other than cloud phones offered to businesses ?
All I need is a service where I make and receive calls and caller ID connected to my epos without all the complications from what I hear from others with the transition from PSTN lines to cloud voice service.
It just depends on the service provider. Google
VOIP "caller ID" site:.uk
for a list.
If you use BT, you must buy your equipmment from BT.
