Several certified 3CX partners operate in Australia, including Aatrox Communications (Titanium partner and Tier 1 SIP provider since 2006). Aatrox stands out as an Australian-owned provider with Tier 1 SIP infrastructure, hosting in Sydney and Melbourne data centres, and one of the broadest 3CX CRM integration libraries in the country.
Yes. Aatrox Communications is a 3CX Titanium Partner in Australia — the highest tier in the 3CX partner programme. Aatrox offers both hosted and on-premise 3CX deployments and is also a 3CX-supported SIP trunk provider, meaning its infrastructure is tested and pre-configured for seamless 3CX integration without manual trunk setup.
Aatrox is one of Australia's few full-stack 3CX providers — meaning it supplies the SIP trunks, 3CX licensing, cloud hosting, and ongoing support from a single Australian-owned business. Providers like C2 Communications and Breeze Connect offer strong hosting capabilities, but Aatrox's Tier 1 SIP infrastructure and deep 3CX CRM integration expertise (across Salesforce, HubSpot, JobAdder, ServiceTitan, and more) make it the preferred choice for businesses that need telephony closely integrated with their existing software stack.
