The problem

Every missed call is money walking out the door.

Most service businesses lose 30–50% of inbound leads because no one picks up. After hours. During jobs. On lunch. Customers don't wait — they call the next number on Google.

62%
Of inbound calls go unanswered

At small service businesses, more than half of calls miss their target.

80%
Of callers won't leave a voicemail

When they hit voicemail, they hang up and call your competitor.

$1,200
Average value of one missed lead

For a service business, every uncovered call is real revenue lost.

Common questions

Quick answers.

Will the AI actually sound human?
Yes. Eva uses a natural-sounding voice and conversational LLM responses. Most callers don't realize they're talking to an AI unless told. If asked directly, Eva is honest about being an AI receptionist — that's a hard rule.
How long does setup really take?
Five minutes. Paste your website URL, pick a phone number, and forward your line. Eva starts answering immediately.
Do I need to change my phone number?
No. Keep your existing number. Forward calls to OnCall's number when you can't answer. We have a quick guide for every major carrier.
What if Eva doesn't know the answer?
She says so honestly, captures the lead, and texts you to call back. She'll never make something up. You can edit her knowledge base any time.
What does a typical month cost?
Most HVAC and plumbing customers spend $40–$120/mo total. 20 inbound calls per week (3 min avg) ≈ $58/mo. Your first phone number is free for 30 days, after which it's $10/mo.
