Real Voices for the Calls Your Voice Agent Can't Take.

• Callers reach a person when the call needs one
• Overflow has somewhere to go instead of a dead end
• Each call comes back with notes your system can use

1. A clinic's AI receptionist answers routine calls but transfers callers who ask something outside its script to a human, who answers from the clinic's approved information or takes a message.
2. A home services company's voice agent cannot handle more simultaneous calls in a storm week. Overflow calls route to human callers who log each request for the company's dispatcher.
3. A business wants follow-up calls made to its own customers who opted in to be contacted. Human callers make the calls from a script the business approves and record each outcome.

Takes the transferred call, follows the approved script, resolves or logs the call, and hands back a written summary.

Every request is reviewed by a person. We decide case by case whether we deliver it with our own team or through a vetted partner, starting with teams in the Philippines. If a job isn't something we can do well or lawfully, we'll tell you plainly.

Human callers answer inbound calls your voice agent hands off or cannot take, and make outbound calls only to people with lawful consent, which is the customer's responsibility.

Can a human take over a live call from my voice agent?

That depends on your telephony. Tell us how your voice agent can transfer or hand off a call (phone number, SIP or callback) and we assess what can be arranged. Nothing is connected automatically today.

Do you handle outbound calls?

Only to people who have given lawful consent to be called. Holding that consent is your responsibility; describe it in consent_record and set call_direction to outbound_consented. We do not provide call lists and we decline campaigns that look unlawful.

What does my system get back after each call?

Once an arrangement is running, each call returns a call_id, a disposition, a written summary, whether a callback is needed and a recording reference where recording is agreed. A structured API is planned.

Is there a minimum number of calls?

We do not publish minimums. Describe your expected volume and hours and we review whether we can deliver in-house or through a vetted partner.
