Moving from ISDN to SIP
Following the 2025 Stop Sell milestone in September 2023, ISDN is now effectively end-of-life as it is no longer being supported. Therefore customers can no longer change their current ISDN set-up.
Cost alone is a big enough reason to migrate but with SIP being feature rich in terms of flexibility and management, there are a number of reasons for customers to to move to SIP now
before ISDN is actually switched-off.
