Numbers & SIP Trunks

Phone Numbers and SIP Trunks for AI Agents

Get your AI agents on real phone numbers — buy a new one, bring a number you already own, or port your existing numbers across with the paperwork handled in the platform.

Numbers connect to agents through SIP trunks, so calls route to an AI agent, to your PBX, or to a person, depending on what the number is for.

Keeping the number matters more than people expect: it is printed on your vans, your invoices and every listing you have ever paid for.

The numbers

Three ways to get a number onto an agent

Buy one, bring one, or move the one you have.

Search available numbers and buy one outright when you want a new line for a campaign, a location or a department. It is live and attached to an agent in minutes.

Already have a number with another provider? Import it, and it works with your agents without moving your telephony contract.

Or port properly. Raise a porting order, upload the paperwork the losing carrier requires, and submit it — all tracked in one place rather than conducted by email with someone who does not answer.

Porting is the part most people dread. It is also the part that makes the change invisible to your customers, because the number they have always called still rings.

What you can do

Six things you can do with numbers here

From buying a line to routing it where it should go.

Search and buy a number

Find an available number and put it live on an agent, without a procurement conversation or a new contract.

Bring a number you already own

Import an existing number so your agents can answer it, without moving your telephony arrangements first.

Port your numbers across

Raise a porting order, upload the required documents and submit it, with the status tracked instead of chased.

SIP trunks to your systems

Trunks connect numbers to agents, to your PBX, or to both, so calls arrive wherever they should.

Route a number to an agent

Point a number at a specific agent, so a campaign line and a support line behave completely differently.

Release what you stop using

Numbers you no longer need can be released, so you are not paying for lines nobody dials.

Worth knowing

Why numbers decide how fast you can start

Telephony is usually the slow step, not the AI.

Teams evaluating AI agents normally get stuck on the phone line rather than the agent. The number belongs to a carrier, the contract has months left, and nobody wants to risk the main line on an experiment.

Buying a fresh number sidesteps all of it. Run the agent on a new line, point some traffic at it, and decide with evidence instead of a meeting.

When it works, port the real numbers across and the change is invisible from outside — same number on your vehicles, your invoices and your listings, answered differently.

That sequence, new number first and port later, is how most of these projects actually succeed.

Questions

Common questions about numbers and trunks

What people ask about getting agents onto real lines.

Yes. Either import a number so agents can answer it, or port it across properly — raise the order, upload the paperwork and submit it, with the status visible throughout.

A newly purchased number can be searched, bought and attached to an agent straight away. Porting an existing number takes as long as the losing carrier takes.

No. A number can be imported or trunked to work with agents while the rest of your telephony stays where it is. See SIP extensions for putting an agent behind your existing PBX.

Yes. Each number can point at a specific agent, so a campaign line, a support line and an out-of-hours line each do their own job.

Release them and they stop billing. There is no benefit in holding lines nobody calls.

Wherever you route them — an AI agent, your PBX, or a person. See AI agents for what happens once a call is answered.

Put an agent on a real line

Start with a new number; port the rest when you are convinced.
