After Hours & Overflow
After hours answering service that answers, not records
Your phone keeps ringing after the team goes home, and at noon when every line is busy. Sono picks up each of those calls, books the job, takes a proper message and puts real emergencies through to your on-call person.
An after hours answering service picks up your business phone when your team is off, so callers get an answer instead of voicemail. Sono's AI voice agent answers every call 24/7, books appointments, takes messages and escalates true emergencies to the person on call.
How it works
How does an after hours
answering service work?
From the first ring to the morning handoff, in four steps.
Step 01
The call arrives
Your line forwards to Sono when you are closed or busy. It answers on the first ring in your company's name.
Step 02
It handles the request
Books into your calendar, answers from your knowledge base, or takes a structured message. Not a recording.
Step 03
It escalates by your rules
Emergencies ring your on-call person. Urgent but not critical calls get a text. Everything else waits for morning.
Step 04
Your team gets a digest
Caller, reason, outcome and next step for every overnight call, waiting in the dashboard and, if you like, your inbox.

Escalation
What happens to an emergency call at 2 a.m.?
You decide which calls wake someone up, once, during setup. Sono sorts every after hours call into one of three lanes and acts on it before the caller hangs up.
| Lane | Example caller | What Sono does |
|---|---|---|
| Emergency | "Water is coming through the ceiling." | Confirms the address and callback number, calls your on-call person right away and transfers the caller if they pick up. |
| Urgent | "The heating stopped, but we are fine until morning." | Takes the details, texts your on-call person, and tells the caller a time window for the callback. |
| Routine | "Can I book a service for Thursday?" | Books it, sends a confirmation by WhatsApp or SMS, and adds it to the morning digest. |
Sample opening script (the call comes first, the follow-up second)
Sono: "Good evening, you've reached [Business]. The office is closed, but I can help right now. Is this an emergency, or would you like to book or leave a message?"
Sono, after an emergency answer: "Thank you. I'm calling our on-call technician now. Please stay on the line. If it doesn't connect, they will call you back within ten minutes."
The wording, the lane definitions and the callback windows are yours to set. Sono follows them exactly.
What you get
What is the difference between
after hours and overflow coverage?
After hours coverage answers when the office is closed. Overflow coverage answers when it is open but every line or person is busy. Sono does both from one setup, so a lunch rush and a Sunday night get the same quality of answer.
Sono writes appointments straight into your calendar. The customer hears a confirmed time, not "we'll call you back."
Leak, fire, medical or security keywords trigger a call to your on-call contact. Anything else is queued for the morning.
The caller gets a live conversation. Confirmations and photo requests can follow on WhatsApp or SMS, which is where many customers prefer to continue.
Every overnight interaction summarized with caller, intent, outcome and the follow-up your team still owes.
No on-call rota for routine calls, no overtime and no bureau contract with a minimum term.
How much does an after hours answering service cost?
Human bureaus usually charge per call, per minute or as a monthly bundle with a minute allowance, so the bill follows your call volume. Sono is priced per minute of conversation, from €0.30 to €0.40 per minute for a fully managed deployment. A business that gets 40 after hours calls a month averaging three minutes each uses 120 minutes, which is €36 to €48 at that rate. Your own numbers will differ, so ask for a quote built on your call log.
