How to divert dental practice calls while keeping your number

Keeping a number is different from moving it

Keeping your published practice number may be possible by forwarding selected calls to an answering service. This is different from porting the number to another provider. Compatibility, destination numbers, contract terms and charges need checking with the company that manages your telephone service.

Begin with the number patients actually dial. Ask where it terminates: an individual user, a group of handsets, a queue or an automated menu. A setting on one receptionist’s extension may not control calls to the main practice number.

This guide is a planning checklist by ClinicVoice, not evidence that your telephone system has been connected. A successful browser voice demo tests conversation; it does not test your number or call diversion.

Choose the route that matches the problem

BT’s Cloud Voice documentation distinguishes busy, no-answer, always-on and unreachable forwarding. It also describes selective rules based on time or date. These are provider-specific examples; another product may use different settings.

Busy-line cover

Discuss what the system treats as busy. Ask how call waiting, spare handsets and queue capacity affect whether the overflow route is reached.

No-answer cover

Agree how long reception should have to answer. Check whether voicemail or a queue timeout takes over first.

Closed-hours cover

Confirm the practice schedule, bank holidays and which timezone the telephone system uses. Check the return to the normal daytime route.

Unreachable fallback

Agree what should happen if a handset, internet connection or destination cannot be reached. Include a route your team can restore.

BT notes that always-on forwarding overrides its other forwarding options. Have the provider confirm rule priority before changing a live number; forwarding every call may differ from the limited overflow cover you intended.

Questions to send to your telephone provider

You can adapt this checklist into a short support request. Include your product name and main number through your provider’s normal secure support route.

1. Which object controls our main number? Identify the user, hunt group, queue or menu, and the person authorised to change it.
2. Can we divert only the selected calls? Specify busy, unanswered or closed-hours cover and ask which existing rules take priority.
3. What happens to caller identification? Confirm which number the answering service receives. Do not rely on caller ID alone as the caller’s preferred callback number.
4. What are the charges? Ask about feature fees, the forwarded call leg, destination rates, minimum charges and concurrent calls. Confirm whether bundled minutes cover the divert.
5. How do we reverse the change? Record the previous settings and agree who can restore them, including when the usual administrator is away.

Ask for the answers in writing. They form the provider side of the setup; the answering service separately confirms its destination, capacity and agreed scope.

Budget for the telephone route as well as answering

The answering subscription and telephone forwarding can be separate costs. For example, BT’s phone-line diversion guide states that its diverted call leg is charged at standard dialling rates. It also limits those instructions to phone lines and points other products to different guides. That does not establish the rate or method for your particular contract.

Compare your provider’s written charges with the answering service’s subscription, setup, included usage and extra minutes. Keep any SMS, transfers or appointment-system work separate until quoted. Our UK dental answering cost guide shows ClinicVoice’s published prices and worked examples.

There is no need to change the number shown on your website merely to test an agreed divert. Confirm that the original route and contract remain in place before accepting that arrangement.

Test the agreed routes before launch

The following is a proposed acceptance record, not a report of completed ClinicVoice tests. Use fictional caller details and a test window agreed with the practice and provider.

For each result, record what actually happened rather than ticking a whole system as working after one successful call. If a route differs from the plan, resolve that specific issue and repeat the affected test.

Connect the route to a useful reception handover

A call reaching Alice is one part of the workflow. Agree what she should collect, where the record should go and who will act on it. Use the reception handover checklist to plan that next stage.

For ClinicVoice, email summaries, SMS, routing and diary connections require an agreed configuration and separate testing. Reception follows up and confirms appointments unless a compatible booking integration has been agreed and tested. The practice defines its urgent-call process; Alice does not make clinical decisions.

Send your practice website and the cover you need. Aleo can then discuss the provider details needed to assess feasibility and prepare a scope.
