Like VAPI — built better for Australia
Same idea: deploy AI voice agents that call, qualify and book. Different reality: sovereign AU infrastructure, ACMA/DNCR-aware calling, SMS in the same workflow, and Fulcrum Cortex so operators run it from the channel they already live in.
VAPI-class agents
Deploy natural voice agents for outbound, inbound and WebRTC — the same category as VAPI, without the US-only trade-offs.
Calls + SMS together
Qualify on the phone, then lock the outcome with SMS confirmations, no-answer texts and booking links.
AU compliance by default
ACMA calling windows, DNCR washing, Privacy Act alignment and all-party recording consent — not bolted on later.
Cortex in the loop
Sessions orchestrates; CRM logs the outcome; your channel gets the recap. Voice is a fleet specialist, not a silo.
Same category. Stricter home ground.
If you know VAPI, you already understand Lyre: programmable voice agents, low latency, BYO models. Lyre wins when you need that power on Australian soil — with SMS, compliance and Cortex orchestration included in how the business actually runs.
| Capability | Fulcrum Lyre | VAPI |
|---|---|---|
| Category | Voice agents API + operator fleet | Voice agents API |
| Data residency | Australia (Sydney / NEXTDC path) | US-centric by default |
| Telephony | AU SIP (e.g. Symbio) + WebRTC | Global / US-first carriers |
| Compliance | ACMA, DNCR, Privacy Act baked in | You own AU compliance |
| Latency target | Sub-500ms voice-to-voice | Fast — varies by stack |
| Sovereign models | SCX.ai path available | BYO cloud models |
| SMS in the loop | Call + SMS cadences under Cortex | Voice-first; SMS is DIY |
| Operator UX | Command from Discord / Telegram / WhatsApp / Slack | Dashboard + API builders |
| Best for | AU teams who need VAPI power + local trust | Builders shipping global voice apps |
Positioning for operators evaluating a VAPI alternative in Australia. VAPI remains a strong global builder platform; Lyre is the better fit when residency, ACMA/DNCR, SMS cadences and channel-native ops matter.
Build on lyre.au
The Australian Voice API — agents, PSTN + WebRTC, sovereign path via SCX.ai. Cortex is how your team commands those agents as one fleet member alongside Code and CRM.
