Make local, national, mobile, international and special service calls with TPG's ISDN (for multiple phone lines) and PSTNs. These premium quality services utilise:
  • TPG's carrier-grade voice and data network for calls within Australia
  • TPG's partnerships with leading overseas networks for international calls
  • Multiple PSTNs via the NBN where the service is available.
TPG's ISDN is especially useful for high call traffic applications such as those generated by PABXs. Call centres and companies with high call volumes can
choose multiple 30 channel connections with flexible pricing packages and advanced support.



Your ISDN can be configured to support either 'both way' or
'outgoing call traffic' only. You can also redirect incoming calls
from a single or range of numbers to an alternative number
during a scheduled business event or emergency. Your PSTNs
can be delivered via Telstra Rebill or TPG voice using NBN
Access/NTUs up to 8 PSTN where NBN Access is available.

Cost savings and support

Access a range of highly competitive voice call rates and
pricing plans; simplify your carrier management with one
provider, one bill and one point of contact; save on installation
and reduce your Access rental costs; and receive 24/7 support
to minimise hassles and improve business continuity.

Separate data calls

Use your ISDN connection for data applications via incoming
and outgoing switched data calls at 64Kbps.

Easy transition

TPG supports number porting from all major carriers
and can also provide new number options.

Comprehensive reporting

Web-based reporting can let you drill down ISDN calls
to individual call details.
