Key takeaways
- Customers should keep dialling the number on your van, site, and Google profile.
- Call forwarding sends unanswered calls to CallAid without a public number change.
- Conditional divert (*61 style setups) rings you first, then AI on the miss.
- Test before go-live so network voicemail does not beat your divert.
- You can turn divert off instantly if you need calls back on the handset only.
Your number stays the same
Customers save your number in their phone, print it on vans, and click it from Google Business Profile. Changing that number for a new phone system destroys trust and local SEO equity. CallAid is designed so you keep the number people already know.
Technically, that usually means call forwarding or a SIP/routing layer — not asking the market to relearn a new digits string overnight.
- Customers keep calling your mobile or landline. Nothing changes for them.
- Call forwarding sends unanswered calls to CallAid when you cannot pick up.
- You do not need a new number on your van, website, or Google Business Profile.
Missed-call forwarding that fits how you work
Most UK small firms start with “forward when unanswered” or “forward when busy,” so live answers still come from you. Out-of-hours, forward all calls to AI. That pattern matches how trades and clinics already think about cover.
Confirm with your mobile or VoIP provider how long the ring time is before forward triggers — too short and AI steals live calls; too long and callers hang up.
- Missed-call forwarding (*61) only rings CallAid when you do not answer. Your line rings first, then the AI picks up the miss.
- Use the timed *61 code in setup so CallAid answers before your network voicemail kicks in.
- Test with a colleague's phone before you go live so you know exactly what the caller hears.
A short onboarding checklist
Write your greeting, qualification questions, urgent transfer rules, and notification contacts before go-live. Test from a personal mobile that is not the business line. Place a real enquiry as if you were a customer.
Update internal staff so nobody disables forwarding “temporarily” and forgets to turn it back on.
- Sign up and complete your workspace with business name, industry, and services.
- Choose the UK voice that fits your brand and add context the assistant should know.
- If your inbound number changes later, use the telephony resync option in the dashboard so routing stays correct.
Why keeping the number matters commercially
Printed assets, signage, directories, and packaging all amortise slowly. A number change forces a reprint cycle and confuses returning customers. Local pack rankings also associate entity signals with the published phone number.
If you must migrate providers later, port carefully and keep forwarding continuity so AI cover never drops mid-move.
- Reprint costs and Google listing edits are annoying — but trust loss is worse.
- Past customers already have you saved. A new number breaks that habit.
- Marketing assets stay coherent: signs, invoices, uniforms, and ads all match.
Forwarding patterns that work in the UK
Mobiles, hosted PBX, and business VoIP all support some form of conditional forward, but menus differ. Our practical walkthrough is in how to forward calls to an AI receptionist in the UK.
Document the codes or portal clicks you used so any partner can restore settings after a phone reset.
- Missed-call / conditional divert: best default for owner-operators.
- Immediate divert: use when you want AI to answer a dedicated overflow line.
- Time-based rules: useful for known out-of-hours windows if your handset or PBX supports them.

Go-live checklist
Verify SMS delivery, email spam folders, timezone on out-of-hours rules, and emergency transfer destinations. Record a fallback: if AI fails, does the call go to voicemail or another human?
Tell regular clients nothing magical changed — they should simply notice you are easier to reach.
- Complete business name, services, and coverage area in your workspace.
- Pick a UK voice and write escalation rules for urgent call types.
- Place two or three test calls from another phone and confirm what the caller hears.
- Check that summaries arrive before you announce cover to your team.
Next steps
Keep your public number, enable missed-call forward, and run the seven-day trial. Only then consider expanding to always-forward during site blocks.
- Follow setup steps in the Help center.
- Start a trial or contact us if you want a hand getting forwarding right.

Frequently asked questions
- Do customers see a different number when AI answers?
- They dialled your number. The experience is an answered call on that line, not a new public identity.
- What if I use a landline and a mobile?
- You can forward the customer-facing line that matters most, or set rules per line depending on your setup.
- Can I pause AI cover for a day?
- Yes. Disable divert on the handset or pause routing in product settings according to your controls.
- Will this break my existing voicemail?
- Set timing so unanswered calls reach CallAid before network voicemail. Always test.
- Is a new tracking number required?
- No for CallAid's usual missed-call model. Keep the number customers already know.
