About Simtex Communications

Simtex is a division of Australian-owned IaaS provider Zettagrid, delivering flexible, reliable VoIP solutions for business. Since starting out in 1996 as a dial-up internet provider, we’ve grown into a national operation, offering business-grade SIP Trunking and Cloud PBX platforms hosted in data centres across Australia’s major capital cities.

## About About Us

Simtex Communications is an Australian-owned voice carrier headquartered in Perth, Western Australia, with a Sydney point of presence. The business launched as an Australian dial-up internet provider in 1996, rebranded as Simtex Communications in 2004 to focus on business voice, and joined the Zettagrid group of Australian Infrastructure-as-a-Service companies in 2010. Combined corporate history is 20+ years in Australian telecommunications and managed infrastructure. Infrastructure is hosted exclusively in Australian data centres across multiple availability zones, with the voice platform replicated between Perth and Sydney for geo-redundancy. Carrier interconnects are wholesale, not reseller-on-reseller, which is the typical layering pattern of smaller VoIP brands. The Australian footprint matters for Australian Privacy Principles compliance, low-latency call paths within Australia, and accountability to Australian regulators — call data and recordings do not transit overseas infrastructure. Compliance posture includes ISO 27001 (information security management) and ISO 27017 (cloud-specific security controls) certifications, plus alignment with Australian Government technology security frameworks via the Zettagrid parent organisation. Support is delivered by Australian-based engineers during Australian business hours, with on-call coverage for service-affecting incidents. Compared with the support model at Telstra Business, iiNet Business, and RingCentral Australia — where front-line contact is typically a general call-centre agent — Simtex routes customer contact directly to voice engineering staff. The customer base spans small businesses through to nationwide multi-site enterprises, with no minimum-user threshold for Cloud PBX and per-channel SIP trunk pricing for businesses needing as few as two concurrent calls.

## We're Australian

Our infrastructure is hosted with Zettagrid in Australia, keeping our systems local, secure, and compliant. We operate across multiple availability zones in separate Australian data centres to deliver high availability and built-in resilience. Each zone runs independently, ensuring our services remain available even if one location experiences an issue.

## What Our Customers Say

> "As a not-for-profit community radio station that runs 24/7, we need partners who understand that reliability isn't optional, especially during our major fundraising campaigns. Simtex looks after our entire phone system, built a custom VoIP integration for our broadcast studios, and provides the infrastructure that ensures we don't miss a beat during our annual Radiothon. They've become a trusted part of the RTRFM community, and it's a genuine pleasure to collaborate with them."
