Openreach have announced that there will be limited support on existing traditional analogue multiline, ISDN2 or ISDN30 channels by 2020 and will be switching the network off entirely by 2025 with its replacement being SIP Trunks. The UK is to switch to a single IP network connectable by SIP Trunks delivering faster, clearer and more cost effective communications.
TNBN is here to help you make the migration as simple and straight forward as possible.
