Where US businesses lose calls

The calls that go to the next listing

3 hrs
Coast-to-coast is a staffing problem

A five o’clock call in New York is two in Los Angeles. Any business selling beyond its own zone has hours where customers are awake and nobody is answering.

1 tap
Map results dial instantly

Somebody searching on a phone taps the first listing, and taps the next one just as easily. These are your highest-intent callers and your least loyal.

50 states
Recording rules that vary by state

Some states require every party to consent, not just one. A business taking calls across state lines cannot reason about this caller by caller.

What it does

Answers, books, and keeps the record straight

Not an answering service taking messages. It reads live availability and writes the appointment into the calendar your staff already work from.

📍
Your own area code

A 212, a 312, a 415 — or keep the number already printed on your trucks and forward it. Customers dial what they have always dialled.

🌎
Covers every zone at once

The same arrangement answers a seven a.m. call in Boston and a seven p.m. one in Seattle, without anybody being scheduled for either.

📅
Books into your calendar

Google Calendar, Outlook or Square Appointments. The slot is written in as it is offered, so the next caller cannot be given it.

⚖️
Disclosure on every call

Callers are told at the start that the call is handled by an automated assistant and that it is recorded — which is also the practical answer to two-party-consent states.

How we tune it for you

What is different about setting up in the US

The US is among the fastest countries to start in, because nothing has to be approved before a number can be issued. The considerations that remain are about what is said on the call rather than about paperwork.

No documents, no review

US local numbers carry no supporting-document requirement, so there is nothing to submit and no queue. Compare Ireland, where documents must be reviewed before any number exists.

Two-party consent, handled by default

States differ on whether one party or all parties must consent to a recording. Disclosing at the start of every call is the approach that holds in the strictest of them, so it is what happens on all of them.

Saying it is an AI, early

Several states now regulate automated callers, and the wording differs. Telling people plainly in the opening seconds satisfies the intent of all of them and is what stops callers feeling misled anyway.

This is not legal advice

State law varies and changes. If you operate somewhere with specific obligations — healthcare, finance, collections — that is a conversation with your own counsel rather than something to infer from a marketing page.

Questions

Good to know.

How quickly can a US business get a number?

The same day. US local numbers carry no supporting-document requirement, so there is nothing to submit and no review to wait on.

Can I get a number in my own area code?

Yes. Ask for the area code during setup if looking local matters to you — or keep the number already on your trucks and forward it instead.

What about two-party consent states?

Every caller is told at the start that the call is handled by an automated assistant and is recorded. That approach holds in the strictest states, so it is used in all of them.

Do I have to tell callers it is an AI?

Several states regulate automated callers and the wording differs. Disclosing plainly in the opening seconds satisfies the intent of all of them, and is what prevents callers feeling misled regardless.

Does it handle calls across time zones?

That is one of the stronger reasons to use it. The same arrangement answers a seven a.m. call on the east coast and a seven p.m. one on the west, with nobody scheduled for either.

Is this legal advice?

No. State law varies and changes, and if you operate in a regulated field the specifics belong with your own counsel rather than with a marketing page.
