The wholesale voice market depends on network reliability. We know how critical voice reliability is for your business, whether you’re running a national contact centre network, an MSP supporting enterprise clients, or an international telecom provider connecting into Australia.

That’s why Symbio now gives Australian customers the option to enable dual voice carrier redundancy across two completely independent networks: Symbio and Aussie Broadband.


Separate carrier networks

Symbio is one of the few Australian carriers that can connect customers to two fully independent VoIP carrier networks through one relationship.

The Symbio and Aussie Broadband voice networks run on separate infrastructure. This separation underpins their reliability. If one ever hits congestion or downtime, calls can seamlessly switched to the other, keeping your voice services up and running without missing a beat.

Routing control, without headaches

Control and flexibility come standard. You decide how your Dual Network routing works: set one as primary and the other as backup, or balance traffic across both.

Dual network redundancy is managed through a single provider relationship. We are working hard to give you routing flexibility without the usual carrier headaches.



Empowering Australian & International voice providers

Whether you operate nationally or globally, Symbio Dual Network redunadancy sets a new standard for resilient, carrier-grade voice services in Australia.

For international telecom and UCaaS providers, this means you can strengthen your Australian presence and boost reliability without adding new carrier contracts or interconnects.

For local providers, contact centres, and aggregators, it means rock-solid redundancy and geographic diversity, all without juggling multiple carrier relationships or complex routing setups.

In short, dual-network redundancy gives you peace of mind, less operational overhead, and more control, all through one simple connection.

Next steps

Dual network redundancy is game-changer for any UC, CX or SIP trunking provider operating in the Australian market.
