SIP Trunk Australia — +61 Termination & DID Numbers

Australian carriers must block calls with invalid or spoofed CLIs under the ACMA-registered Reducing Scam Calls code, so a valid caller ID is not optional. Number ranges are well defined: 02/03/07/08 geographic, 04 mobile, 1800 freecall and 13/1300 local-rate numbers.

Overview

Routing calls to Australia

Traffic to Australia leaves our SBCs on more than one upstream carrier per prefix. If a leg toward Sydney or Melbourne starts returning 503s or long post-dial delay, the next attempt goes to another carrier automatically. Calls to Brisbane, Perth and Adelaide follow the same failover logic.

ACMA sets the Australia numbering plan, and our prefix tables follow it closely. Supported number types: geographic, national, mobile and toll-free. Inside the country, numbers are dialled with a 0 trunk prefix. Strip it before you send the call, and send 61 followed by the national number.

For inbound numbers in Australia, plan on paperwork: proof of address and company or identity documents are usually required before a DID goes live. Termination needs no documents beyond normal account checks.

What you get

What you get in Australia

One account and one balance, with the same SBCs for termination and inbound numbers.

CLI route tier
Caller ID delivered end to end on +61 calls. Use it for sales, support and any traffic where answer rates matter.
Non-CLI route tier
A lower-cost tier where caller ID delivery is not guaranteed. Suitable for internal or transactional traffic that does not depend on the CLI.
Number types
Geographic, National, Mobile, Toll-free. DID availability varies by range and city.
Codecs
G.711a/u and G.729 on every route, G.722 and Opus where the far end supports them. T.38 for fax.
Channels on demand
Concurrent call limits are set per account and raised as your traffic grows. No fixed channel bundles.
Multi-carrier failover
Every +61 prefix is mapped to more than one carrier. Failed attempts move to the next one automatically.
