ISDN2 is an ISDN (Integrated Services Digital Network) service that allows a business to gain all the advantages of digital phone lines without having to commit to more than 2 lines. ISDN2 enables you to conduct 2 concurrent telephone calls at the same time over the one PSTN line. ISDN2 lines provide clear, high-quality telephone connections, and offer more call and messaging features than standard PSTN business lines. This type of service is ideally suited to businesses that require 2 to 4 telephone lines.
ISDN2 lines use the copper network to deliver phone services. In line with the roll-out of NBN and other broadband infrastructure, ISDN2 is no longer available for new service connections. Commencing September 2019, current services are being gradually disconnected and migrated to IP lines. Business IP lines use SIP (session initiation protocol) to deliver phone lines over the internet.

You can start with a single extension and build the phone system as your business grows.
Although they're both a type of ISDN (Integrated Services Digital Network) technology, there are 2 main differences.
As the name indicates, the number of channels (call lines) available with ISDN2 is two. Multiple services are bundled together to deliver more than 2 lines (in multiples of 2). With ISDN, there is a minimum number of 10 channels and a maximum of 30.
ISDN is a primary rate digital service that requires the PBX to be fitted with a PRI (primary rate interface) card. ISDN2 is a basic rate service and requires the PBX to be fitted with a BRI (basic rate interface) card.
No. The only requirement is for the business premises to have the necessary PSTN wiring and capacity.
Traditional copper lines are required to deliver ISDN2. There is no need to have an active PSTN line but there must be the required PSTN wiring not being used for other purposes.
Yes. And the phone system must be fitted with a BRI (basic rate inteface) card.
Most SME PBX systems can be used for both ISDN and ISDN2. However, they must be fitted with the necessary interface card, which is different for both technologies. To find out is your system is compatible, either check with your PBX maintainer or call us on 1300 000 300.
Yes. However it's dependent upon your telephone system and if it can be programmed to route fax calls to the fax machine. Please consult your PBX technician.

Yes. BusinessCom has LNP (local number portability) arrangements with all major carriers.
When upgrading from a PSTN service, your main business number will be made part of the ISDN2 service. Please note that only your main business number will be retained. When switching your existing ISDN2 lines to BusinessCom, all your existing numbers will be retained.
The ISDN2 network is wholly owned by Telstra, a wholesale provider of BusinessCom. When transferring services, there are no network changes and it's only the billing that gets transferred.
Transferring your existing service to BusinessCom is seamless. All of your existing features and configuration remains as is and you won't even notice when the changeover happens.
