ISDN Switch Off by 2025!
BT have announced that they are ending support for ISDN and
PSTN networks from 2025, although it is expected the transition
will start in 2019 with no new orders being taken and exchanges
What is ISDN and PSTN?
ISDN stands for Integrated Services Digital Network. This is a set of
communication standards which enabled the simultaneous digital
transmission of voice, video, data over the infrastructure and circuits of
the traditional Public Switched Telephone Network (PSTN). ISDN
displaced the traditionally copper fixed-line analogue telephone networks.
A SIP trunk is basically a digital port placed over your existing telephone system to give it a greater degree of flexibility. This ISDN replacement is suitable for businesses which have a phone system which is less than 5 years old.
This advanced product is a speciality at CBG Telecom. Our clever boxes converts your ISDN signals to digital ones. They are suitable for larger businesses which have very old (5+ years) onsite phone systems.
ISDN was an improvement over PSTN when it first arrived, as it allowed simultaneous phone calls over the same line. However, it is now soon to be displaced with new IP based telephony systems that use an IP or Internet connection to enable communication throughout an organisation, different sites, or even different countries. There are currently an estimated 3.2 million ISDN channels in the UK. The vast majority of which are owned by BT. These will all have to be replaced or upgraded to IP based telephony systems in the coming years. While a quarter of businesses are unaware of the upcoming switchover, it's estimated that 96% of businesses who have made the change to IP-based telephony systems have benefitted from cost savings.
