A missed call is a customer who rang your competitor next.

Most small businesses lose more work to the phone ringing out than to anything they do wrong on a call. The number is the cheapest part of fixing that, and the part people spend weeks not getting round to.

01Buying a number

Claim one, and it isanswering this afternoon.

The fastest way to get an agent on the phone. Search the market you want, take a number, and it is attached to your account and live. No porting window to wait out, no carrier contract to sign, and no account with a telephony provider needed at all.

Live the moment you claim it

No porting request, no transfer window, no morning where neither the old line nor the new one works.

Country recorded on every number

Because what is available in one market is not available in another, and pretending otherwise wastes your time.

Line fee held apart from minutes

A per-number monthly fee for the capacity, call minutes billed separately, so you can see which is which.

As many as you need

A number per site, per brand, or per campaign, all answering into the same account.

02For your people

Your reps need numbers too.Those are not agent numbers.

Rep numbers and AI agent numbers are deliberately separate systems, because they are different jobs. A rep's number is theirs: it is the caller ID on their outbound calls, it rings them when somebody calls it back, and it is the number on their email signature.

One number per rep

Assigned to a person and used as their outbound caller ID, so a prospect sees a consistent number rather than one switchboard line shared by the whole floor.

It can be rung back

A personal number is not caller ID only. Inbound routing rings its owner first, so somebody returning the call reaches the person who rang them.

On their signature

The number on an email signature is the number that actually belongs to them, rather than one typed by hand and never updated.

Reassign without a port

A number is assigned, unassigned and moved between people from the same screen. Somebody leaving does not strand a line.

Dial a colleague by name

Because the platform knows who owns which number, internal calls are made from the directory rather than from memory.

Separate from agent lines

Rep numbers and AI agent numbers are different systems on purpose. Changing one never disturbs the other.

03Carriers

Bring your own carrier,or do not think about it.

Buying through us needs no telephony account at all, which is why it is the fastest route. If you already have a carrier, or you need numbers in a market where you hold the relationship, connect that account instead and keep your existing rates.

Carrier accounts you can connect
TwilioTelnyxVonagePlivoBandwidthSignalWire

Agent telephony and the sales dialler are configured separately, so a change to one never disturbs the other.

04Keep your existing line

You do not have to start fresh.

Nobody wants to reprint a van, a shopfront and every directory listing to try an AI agent. Point the number you already advertise at one instead. Nothing is ported, nothing is replaced, and it is undone from the same handset that set it.

busyOnly when the line is already engaged.Catches the second caller while you are on the first.
The setup most businesses actually want

Forward on no answer and on busy together. Your people answer everything they can reach, and the agent catches only the calls that would have rung out or hit an engaged tone. Nobody is replaced, and the missed calls stop being missed.

05Lifecycle

A number you publish is a number you keep.

Every number carries a status, its country, its E.164 form, a monthly fee, a next charge date and a last charged date. The state that matters is the third one.

Provisioning

Searched, claimed and being attached to your account. Seconds, not a working day.

Active

Live and answering. Carries its country, its E.164 form, a monthly line fee and a next charge date.

Grace

A payment failed. The number is held, not released, so a card that expired never costs you the number on the side of your van.

Released

Given up deliberately. Nothing reaches this state by accident.

Why grace exists

A number in grace is held, not released. A business that has had the same line for eleven years does not lose it because a card expired over a bank holiday. That is the entire reason the state is there.

06More than one

Multi-site, multi-brand, one table.

Every number in the account in one list, grouped by country, with the busiest market surfaced. Numbers a client buys or forwards themselves appear on their own. Nothing has to be registered by hand, which is what stops the list going stale.

07What it costs

Two meters, kept apart.

A line fee per number, billed monthly on its own cycle, with the next charge date visible against each one. Call minutes bill separately. Keeping the capacity cost and the usage cost apart is the only way a bill stays legible when you are running six numbers across four countries.

Worth saying plainly

International availability is set by the underlying carrier account’s geographic permissions, not by our software. So we do not say numbers are available everywhere in the world. Numbers are available across our supported markets, and forwarding works from anywhere, which covers the case almost every business actually has.

Forwarding costs nothing on our side. If you keep your existing number and divert it, you pay for the minutes the agent handles and nothing for the line, because the line is still your carrier’s. See what each plan includes.

08And then

A number is only the front door.

Once a call arrives, the rest of the chain runs on its own. What answered is classified, what was said is turned into fields, and the follow-up is raised before the caller has put their phone down.

09In short

Why this is the easy part.

Live in minutes

No porting window, no carrier contract, and no downtime on the line you already run.

Keep your number

Forwarding means nothing gets reprinted. Same vans, same cards, same directory listings.

Humans first

Conditional forwarding reaches the agent only on the calls you would otherwise have missed.

Never lose a number

A grace window holds the line through a failed payment instead of releasing it.

Phone numbers

The questions people ask before they set one up.

Yes, and it is the fastest way to get an agent answering. Search the market you want, claim a number, and it is attached to your account and live the same afternoon. There is no porting window, no carrier contract, and no telephony account of your own required. Numbers are available across our supported markets, and each one records the country it was bought in because availability genuinely varies by market.
