An AI receptionist for the hours you're closed.
We build an AI after-hours answering service — an AI receptionist that answers calls outside business hours, greets callers in your brand voice, triages urgency, captures a detailed message, and escalates true emergencies to on-call staff — so a call at 9pm isn't a lost customer. Built on Retell, VAPI, or Twilio and wired into Obsivara, you see every after-hours call, its cost, and any escalation that failed to reach someone.
- Every after-hours call answered, not sent to voicemail
- Urgent calls escalated to on-call staff immediately
- Structured messages waiting when you reopen
- Missed or failed escalations flagged in Obsivara
AI After-Hours Answering Service, done for you.
Branded greeting & triage
Answer in your business's voice and tone, understand why the caller is calling, and sort routine messages from anything urgent using your own rules.
Message capture & delivery
Take a complete, structured message and deliver it by SMS, email, or into your CRM/helpdesk so the right person has everything when they're back on.
Emergency escalation
For genuine emergencies, follow your on-call chain — call or text the right person now — with a fallback contact if the first doesn't answer.

Build → connect → monitor.
Scope & build
On a short call we scope exactly what you need, then design and ship it around your stack, data, and guardrails — with a fixed plan and timeline before any work starts.
Connect to Obsivara
Every system we build is wired into Obsivara read-only from day one — via native n8n, SDK, OpenTelemetry, or webhook. No proxy in your request path, so it never adds latency or a failure point.
Monitor & improve
You get cost intelligence, health scoring, silent-failure alerts, and a weekly audit — and we keep it reliable and tune it as your usage grows, or hand it over entirely.
Built by us. Watched by Obsivara.
Because we build the AI observability platform these agents run on, monitoring isn't an afterthought — every voice agent ships connected to Obsivara via one read-only API key, with per-call cost attribution, latency and dropped-call detection, and health scoring live from day one. Nothing sits in your call path, so nothing we add can add lag to a live conversation.
AI After-Hours Answering Service — common questions
How does it decide what counts as an emergency?
We define the triage rules and escalation chain with you up front, so 'urgent' means what it means for your business. Obsivara logs every triage decision and escalation, so you can audit and tune what gets someone out of bed.
What does it cost to run overnight?
It runs on your Retell/VAPI/Twilio and model accounts, so telephony minutes and model usage bill to you and scale with call volume. Obsivara tracks after-hours cost per call so an overnight spike is visible, not a surprise on the bill.
