PSTN and ISDN
In 2025, BT will switch off all PSTN and ISDN services. The PSTN (Public Switch Telephone Network) and infrastructure is ageing and with advancements in digital telephony and increased quality and reliability in internet services, these traditional fixed analogue lines and calls will cease to exist. From 2025, all consumers and businesses will use IP based systems to make calls over an internet connection.
SIP and VoIP
IP based solutions such as SIP (Session Initiation Protocol) and VoIP (Voice over Internet Protocol) are now the top alternatives for businesses. These solutions offer greater flexibility and resilience, as well as advanced features such as call management and cost reductions due to lower call charges and generous call packages.
