How it works
Speed and naturalness, together — not one at the expense of the other.
Most AI voice systems are fast or natural. PhoneOpti is built to be both, because callers notice the moment either one breaks. Here's what makes it work.
Sub-200ms turn-taking.
The gap between a caller finishing their sentence and PhoneOpti starting to speak is the single biggest 'tell' in AI voice. Ours sits under the threshold where the human brain starts to notice, so the conversation feels like a conversation.
Natural cadence, not a script.
PhoneOpti uses real turn-taking, small verbal affirmations ('mm-hmm,' 'got it'), and appropriate pacing. It can be interrupted mid-sentence and pick up cleanly — the way a receptionist does.
Any API, any webhook.
Your scheduling tool, CRM, or ticketing system connects with a webhook or an API call. Appointments, tickets, and notes are written as the call is happening — not batched at the end.
Clean handoff, with context.
When PhoneOpti hits something outside its scope — a sensitive conversation, an angry customer, a request for a specific person — it warm-transfers with a summary so your team doesn't start from zero.
Inbound and outbound on the same line.
Confirmations, reminders, follow-ups, and lead callbacks — all initiated by PhoneOpti with explicit consent and mandatory AI disclosure at the start of every automated outbound call.
Every call captured.
Full transcripts and recordings (where legal), searchable and taggable. You can hear exactly what happened on any call, any time.
"Feels like a person, works with what you have, never stops answering."
