In case, you already have the NBN internet service, and you are going to purchase their Business SIP trunk service. Yeastar would be able to interconnect with the Telstra NTU to use the Telstra Business Trunk service. Below is the simple topology of the interconnection.

In the following, we would show the how the settings is configured. If you are not familiar with the NTU settings, please get the help from the Telstra support.

Option 1. Peer Type Trunk

On the Telstra NTU

Setup the Northbound Interface first on the Telstra BSIP server. Go to the menu, NTU Provisioning Wizard > PBX Type = Ethernet (SIP PBX).

Don’t allow overstamping in the NTU config Provisioning Wizard > VoiceGlobal Provisioning Wizard > IPPBX Settings. Then follow the steps:

  • Use Ericsson LG iPECS 2.2/3 type system (Utilize the LG profile).
  • Use “Gateway Attached” Topology and then select Load PABX Profile settings and Load
    device settings.
  • Fill in ONLY the PABX IP address. Don’t Check the Register PBX or Authenticate PBX boxes
    SAVE the config on NTU.

On the Yeastar PBX

Create a SIP Peer Trunk pointing to the NTU IP address you configured on the LAN and use Port 5062 to Register the Trunk instead of 5060
