What happens when something goes wrong
No system is failure-proof. Here's exactly what Voi does at each layer to ensure your calls never drop.
AI failure
01If the agent crashes or times out, the call is automatically transferred to a human or backup number — mid-conversation, with context passed along.
Telephony failure
02If our phone infrastructure has an outage, calls automatically reroute through a secondary carrier, transparently to the caller.
Integration failure
03If your CRM or API is unreachable, the call still completes. Everything is logged and auto-synced once systems reconnect.
Total outage
04Calls route to a fallback destination you define in advance. You're notified immediately, with expected recovery time on our status page.
"This is why we quote 99.99% uptime — the output of four independent failure layers, not a marketing number."

Assumptions used in this estimate
Of the calls Voi recovers (missed + after-hours), we conservatively assume 25% convert into a qualified lead — adjust this if you have your own conversion data. All figures are estimates for illustration and will vary by business.

From calls currently missed or received outside business hours.
