Telstra SIP Connect IP Addresses

If you’re deploying a gateway and interfacing to Telstra’s Australian “SIP Connect” SIP trunk service you’ll need to know a few values. Most of the below you’ll get from the relevant Telstra and/or gateway integration guides.

Each state and territory has its own SBC and Telstra STRONGLY prefers you reference these by their host name and use Telstra’s DNS to resolve this. Their requirement here is that you add a conditional forwarder to your corporate DNS for the “nipt.telstra.com” domain.

Domain DNS forwarder IP
nipt.telstra.com 203.52.0.221 203.52.1.222

The above isn’t to every customer’s liking, or it’s perhaps not something they’re able to do in the required timeframe. Your alternative or temporary workaround is to take the potentially risky step of hard-coding the IP address into the gateway’s Hosts table.

Here’s a table with all of the values you need.

When you’re testing this ahead of commissioning you need to know that Telstra’s SBC address won’t respond to pings – but they’ve kindly provided a separate address that will.

SBC Hostname SBC IP address “Pingable” address Media Range
sbc-vic.nipt.telstra.com 203.52.0.167 203.52.0.161 203.52.0.0 /24
sbc-nsw.nipt.telstra.com 203.52.1.167 203.52.1.161 203.52.1.0 /24

      • Hi Greig,

        We have no idea. We use TIPTs in my company but manage the cubes ourselves. Recently we have had issues with Telstra NBN DOT customers phoning our TIPT service. I was doing a routine check to ensure the SBC/s were on the cube still.

        ssdns1002.nipt.telstra.com -> 10.98.48.154

        Host Port Flags Age Type Address(es)
        ssdns1002.nipt.telstra.co None (temp, OK) 5 IP 10.98.48.154
        ssdns1001.nipt.telstra.co None (temp, OK) 5 IP 10.83.148.154
        sbc-qld.nipt.telstra.com None (temp, OK) 0 IP 203.52.3.164
        _sip._udp.sbc-qld.nipt.te NA (temp, OK) 0 SRV 1 50 5060 sbc-qld.nipt.telstra.com

        Ive asked Telstra what they are and why they are appearing.
