Answers Every Call, 24/7
Nights, weekends, holidays, and while your team is already on the phone. No hold music, no voicemail, no callback queue that never gets worked.
Voice AI / Service 06
Every callanswered.
Missed calls are lost jobs. Sterango builds AI voice agents that pick up on the first ring at any hour, answer real questions about your business, book the appointment, and pass anything urgent straight to a person. We design the conversation, connect it to your calendar and CRM, and keep tuning it after launch.

What goes into the build.
Sounds Like a Person
Natural speech with human pacing. Callers can interrupt, change their mind mid-sentence, or ramble, and the agent keeps up instead of restarting a menu.
Knows Your Business
Trained on your services, service area, hours, pricing rules, and policies. It answers what you would answer, and says it will check rather than inventing something.
Books Into Your Calendar
Live availability from Google Calendar, your booking tool, or your scheduling system. The appointment is on the books before the caller hangs up.
Knows When to Get a Human
Emergencies, angry callers, existing customers with a problem, and anything outside its scope get transferred to your line or escalated by text on your rules.
Full Record of Every Call
Recording, transcript, and a short summary after each call, pushed into your inbox or CRM. You see exactly what was said and where the lead came from.
Keeps Your Number
Forward your existing business line or run the agent on a new number. Caller ID, voicemail fallback, and after-hours routing stay under your control.
Handles Spanish
The agent can switch languages mid-call when a caller needs it, without a second phone tree or a separate number.
Screens the Junk
Robocalls, spam, and cold sales pitches get filtered out instead of interrupting your day or filling your voicemail.
Why Sterango
Built around your requirements.
Off-the-shelf AI receptionists read from a generic script and hand you a transcript. That is fine until a caller asks whether you service their zip code, what you charge for a diagnostic, or whether you can come out tonight, and the agent has no way to know.
We build the agent around how your business actually runs. The service list, the pricing rules, the escalation triggers, the calendar it books into, and the exact point where a person should take over are all decisions we make with you before the agent takes a call.
Pricing is a one-time build fee to design, connect, and test the agent, then a flat monthly that covers the calling minutes, hosting, monitoring, and ongoing tuning. No per-lead charges and no per-booking cut.

How it works
A clear path from first conversation to launch.
Listen to Real Calls
We go through how your calls actually go: what people ask, what makes a caller worth booking, and what your team wastes time repeating.
Build the Conversation
We write the agent, pick the voice, load in your services and policies, and connect it to your calendar, CRM, and transfer lines.
Test Before It Goes Live
We run it against real scenarios, including the difficult ones, and tune until it holds up. You approve it before a customer ever hears it.
Launch and Keep Tuning
We forward your number and monitor transcripts. Every month we fix what the agent got wrong and add what it should have known.

Common questions
Questions we get asked.
Will callers know they are talking to AI?
Most will not, at least not immediately. The agent speaks naturally and handles interruptions. We do not pretend it is a person — if someone asks directly, it says so, because being caught lying costs more than being AI.
What happens if the agent cannot answer something?
It says it will find out and passes the call to you rather than inventing an answer. Emergencies, angry callers, and anything outside its scope transfer on rules you set, so the failure mode is a human, not a wrong answer.
Can it use my existing business number?
Yes. You can forward your current line to the agent or run it on a new number. Caller ID, voicemail fallback, and after-hours routing stay under your control either way.
How long does it take to set up?
Usually a week or two. Most of that is learning your business properly — services, pricing rules, service area, and how you want calls handled. We then tune it in the first month based on real calls, not assumptions.
