September 23, 2024Openreach has announced it will be switching off its PSTN and ISDN networks in 2025 in favour of IP voice services, with a gradual phase-out of the older systems. At this point, Openreach will cease taking ISDN orders, and all businesses will be forced to find other IP-based options for their business telephony systems.
Starting September 2023, the UK will no longer support installations or additions to ISDN or PSTN services. The Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) are traditional telecommunication systems, with PSTN being the primary analogue voice communication network and ISDN allowing digital transmission of voice, video, and other services. However, these systems are now outdated, with a 30% decline in ISDN use over the past five years and 25% of UK businesses unaware of this phase-out. The shift to IP-based services like SIP and VoIP, which offer more flexibility and cost-effectiveness, is crucial for businesses to adapt to modern telecom needs. This transition is part of the broader move to cloud-based systems, necessitating robust internet connections to support enhanced features and reliability. ISL provides comprehensive management of broadband, mobile, and internet connections, aiding businesses in this transition. For detailed information, you can visit the provided link.
