Can I keep my business phone number with an AI phone agent?

By Leif Johansen, founder of Digital Macaroni · Updated

Short answer

Yes. You can port your existing number over so the agent answers it directly, forward calls from your current number to the agent all the time or only after hours, or keep your phone system and route calls to the agent. We work with Twilio, Telnyx or the phone system you already use.

Three ways to keep your number

OptionHow it worksGood for
Port the numberYour number moves to a voice provider such as Twilio or Telnyx, and the agent answers it directlyBusinesses that want the agent as the main line
Forward callsYour current provider forwards calls to the agent’s number: always, after hours, or when nobody picks upTrying it out, or covering only missed and after-hours calls
Route from your phone systemYour existing phone system sends certain calls to the agent, such as one option on a menuBusinesses with an office phone system they want to keep

Moving a number between providers in the same area is your right in the US; the FCC’s porting guide explains how it works. Keep your current service active until the port completes, so the number never stops working.

Texting from your number

If your agent sends texts, US carriers require the number to be registered for business texting (known as A2P 10DLC) first. Registration has its own carrier fees, listed by Twilio. We handle it for a one-time $50.

A common way to start

Forward only the calls you’d otherwise miss: after hours, or when nobody answers within a few rings. Your team keeps answering as normal, and the agent catches everything else. Many businesses move the whole line to the agent once they’ve seen it work.

Common questions

Can I keep my existing business number?

Yes. You can port it to a voice provider such as Twilio or Telnyx, forward calls to the agent, or route calls from your current phone system.

Can the agent answer only after hours?

Yes. Your provider can forward calls to the agent after hours or when nobody answers, while your team takes calls as usual.

Do I need to register my number to send texts?

In the US, yes. Business texting from local numbers requires A2P 10DLC registration with the carriers. Digital Macaroni handles it for a one-time $50.
