With Telstra due to cease the sale and to exit ISDN2, ISDN2 Enhanced, ISDN10/20/30, Customers have been left stranded.
Disconnection of existing services for the Products to follow nbn co’s rollout region disconnection timeframe, starting from June 2019, Telstra has decided to exit Products across all geographic regions by 2022.
This may actually be a blessing for many businesses, as ISDN was such a large expense.
The best option if changing from ISDN, is to move to SIP Trunks (Internet based phone lines)
This option is not only very cost effective, but extremely flexible.
Below is rough costing to migrate your current ISDN line to SIP with us.
