Traditional Phone Lines

PSTN and ISDN Phone Lines Are Being Phased Out

In line with the roll-out of NBN and other broadband infrastructure, both PSTN (traditional copper lines) and ISDN (digital phone lines) are being decommissioned and gradually replaced by IP lines. IP phone lines use VoIP (voice over internet protocol) for residential lines and SIP (session initiation protocol) for business lines.

ISDN Line Disconnections and Migration to IP Lines

Commencing September 2019, current ISDN services are being gradually disconnected and migrated to IP lines. Call us on 1300 000 300 for more information and to discuss the best options for your business. CLICK HERE to make an online enquiry.
