The practical answer is that every call gets answered — Ava picks up 24/7 and escalates emergencies per your rules, so the "missed emergency call" scenario is what the service is built to prevent. Where responsibility sits legally is spelled out in the service terms, and that's a your-attorney question, not a marketing promise.
Let's separate the two things owners are really asking here: does it work, and who's on the hook if something goes wrong.
Ava's whole job is to answer when a human can't. A trapped car at 6 a.m. or a snapped spring at midnight gets picked up, triaged as urgent, and pushed down your escalation path — a call, a text burst, or a live transfer to your on-call tech, however you set it.
Because there's no queue and unlimited concurrency, a storm surge that would jam one phone line still gets every caller answered. That's the point: the emergency call that used to hit voicemail and go to the next shop now reaches you.
If you want the full picture of how that coverage works, see how after-hours and emergency answering is set up.
No software vendor — for answering services, dispatch, or anything else — signs up to be liable for the outcome of your customer's emergency. What any given service is and isn't responsible for is defined in its service terms and agreement.
That means the honest answer to "is the service liable" is: it depends on the terms, and this is a plain-language overview, not legal advice. Before you rely on any provider for emergency coverage:
What we can say plainly is how the system behaves: it answers, it triages, it escalates by your rules, and it hands you the details in seconds so you can act. Managing the risk of a missed emergency is exactly why it exists — the terms cover the legal responsibilities, and the technology covers the calls.
