Signalling technology must be All IP-compliant
During 2020 British Telecommunications has begun vigorously pursuing its goal to convert its entire traditional UK public telephone (PSTN) network to an internet protocol (IP) based system – known as the All IP project – by 2025. This process has important consequences for businesses and homes which use telephone network-based monitoring of security (intruder alarm/access control/CCTV) and fire alarm systems connected to alarm receiving centres. Some customers may recognise they are involved with this process because they have a BT classification as receiving Special Services via their phone lines.
