With the rollout of the nbn network across Australia, businesses whose voice services are on ISDN or PSTN now have a high-quality, IP-based voice service alternative.
The introduction of Telstra Business SIP means crisp, clear and reliable voice calls. The service is compatible
with your existing PABX, while providing nbn connectivity.
This is a premium quality service – with more features and options than existing ISDN or Telstra PSTN services. Importantly, we’ve also made it highly flexible so that it grows as your business does.
