Do I need to port my number to use an AI receptionist?
No. You don't need to port your number to use an AI receptionist. You can keep your number with your current carrier and forward calls to Reception One, either all the time or only after hours and when your line is busy. Porting moves the number itself to a new provider, and it's a separate decision.

This guide is written for US service businesses (home services, legal, salons, real estate, auto and similar), so prices are in USD. The forwarding idea itself is the same wherever you are.
What's the difference between forwarding and porting a number?
The two get mixed up because both let customers keep dialling the number they already know. They work very differently.
| Call forwarding | Porting | |
|---|---|---|
| What it does | Your carrier sends incoming calls on to another number | The number itself moves to a new provider |
| Who still holds the number | Your current carrier | The new provider |
| Your current phone service | Stays in place | Is replaced for that number |
| Can you undo it? | Turn the forwarding setting off | You would need to move the number again |
| Needed for an AI receptionist? | No | No |
Think of forwarding as redirecting your mail and porting as moving house. For getting an AI to answer your phone, redirecting is enough.
Can I keep my existing business number with Reception One?
Yes. Reception One's own FAQ answers "Do I need a new phone number?" with: "No. Keep your existing number and forward calls to R1, all the time or only after hours and when your line is busy."
That gives you a simple way to choose how much the AI handles:
- All the time. Every call to your number goes to the AI receptionist.
- Only after hours and when your line is busy. Your team answers as usual, and the AI picks up when you're closed or the line is engaged.
You can also skip your existing number altogether. Reception One's setup starts with "Generate a business number from our dashboard, or forward your existing line." A generated number is useful if you want a separate line for the AI, or you'd rather not touch your current carrier settings at all.
Either way, the AI receptionist does the same job. It answers 24/7, books appointments (live on Cal.com, or as requests your team confirms), answers questions from your knowledge base, recognises urgent calls and transfers them, takes messages, and emails you a call summary.
When does it make sense to port instead of forward?
Most businesses never need to. Porting is worth considering only if one of these is true:
- You want to cancel your current phone service entirely and have the number live with a single provider.
- Your current carrier's forwarding options don't give you the setup you want.
- You're already planning to change phone providers, and moving the number is part of that project.
None of these is a requirement for using an AI receptionist. If you're unsure, start with forwarding. Forwarding is a setting on your line, and you haven't changed who holds your number.
Reception One's two setup options are forwarding your existing line or generating a business number from the dashboard, and neither involves porting.
How do I set up call forwarding to an AI receptionist?
Reception One says you can go live in less than 30 minutes once you've tested your agent. That figure describes the whole setup, not forwarding alone, and how long the forwarding step takes depends on your carrier.
A practical checklist:
- Decide the mode. All calls, or only after hours and when your line is busy.
- Set up the agent first. Add your FAQs, hours and booking options, then test it with real questions before any customer reaches it.
- Turn on forwarding with your carrier. Use your carrier's call-forwarding setting, and point it where Reception One tells you to.
- Make test calls. Call your business number from a different phone and listen to what a customer hears.
- Check the summary. Confirm the post-call email arrives with the recording and transcript, and that it reads the way you want.
- Switch on the real thing. When the test calls sound right, leave forwarding on.
What should I check with my carrier first?
The steps for forwarding differ from carrier to carrier, and we can't speak for any of them. Before you switch it on, ask your carrier about:
- Fees. Whether forwarded calls cost anything extra on your plan.
- Caller ID. Whether the caller's original number comes through on forwarded calls, or your own number shows instead. This matters if you want to know who called.
- Voicemail. Where voicemail goes once forwarding is on, and what happens to messages already stored with your carrier.
- Emergency calling. Whether anything about your line changes for emergency calls if you forward it or move it.
- Your rules. What your carrier and the regulator say about forwarding and porting where you are. For the US, check your carrier or the FCC. This post doesn't cite any rule, because the right answer depends on your carrier and your line type.
We haven't tested every carrier and can't promise how a given one behaves, so treat this as a list of questions, not answers.
