If you have an ISDN line, it is important that you know that all ISDN lines
will be gradually disconnected by 2020 as per the schedule below:



Full cease sale on new
or additional ISDN services
for all customers.


Disconnection will
commence for existing
ISDN connections.


All ISDN connections will be disconnected, and the entire ISDN network will be decommissioned.

Ordering a new ISDN service will no longer be available. Customers will still be able to make configuration, software and record changes to existing services.



Starting from June 2019, existing ISDN services will start to be disconnected. This will be occurring in a phased approach and will follow NBN Co’s rollout region disconnection timeframe.




Acting now will ensure you are taking advantage of the benefits of SIP Trunking
plus avoiding future disconnections that may disrupt your business.
