Vobiz Telephony Infrastructure

Standard voice infrastructure was built for humans making phone calls, not for AI agents holding a real-time conversation - and that gap shows up the moment a voice agent goes into production. Vobiz Telephony Infrastructure was designed for that difference from the ground up, running more than 75 million calls a month at roughly 80 ms of average latency. That starts with the numbers themselves. Local, national, or toll free numbers go live in under 10 minutes across 130+ countries, with outbound reach to 190+. Every number is tracked after going live too, not just delivered. Vobiz customers see roughly a 30 percent reduction in spam flagging on their numbers, because number health is monitored continuously rather than left to chance. From there, the same number runs the full call: SIP trunking, programmable voice, call routing and control via webhooks, and call transfer to a live agent when the conversation needs a human - supported over both SIP and real-time streaming, so a handoff from AI agent to human doesn't drop context mid-call. The same infrastructure also puts voice inside a website or app directly, so a customer can call or be called without downloading anything. Because numbers, calling, and in-app voice sit on one platform, teams get SIP trunking and programmable voice on the same number, without fragmenting call history or customer identity across multiple vendors. Security and compliance sit in that same layer. ISO 27001, SOC, GDPR, and HIPAA coverage, encrypted media, consent signalling, and PII redaction come standard.

The platform is designed to be lean, easy to use, and more affordable than legacy providers, stripping away complex bundles and unnecessary features to focus on what Australian businesses actually need: reliable message delivery at a fair price.

A free dedicated virtual number is included after the first credit purchase, enabling two-way SMS messaging at no extra cost — a feature most competitors charge $19+ per month for. All messages are delivered 100% directly to Australian mobile carriers via a tier-1 carrier network connection, with no offshore routing. The platform's servers are hosted in Sydney, Australia on Digital Ocean infrastructure, ensuring data sovereignty and compliance with Australian privacy regulations.
