Phone, broadband & AI call-answering self-help guide
Review business connectivity and call handling step by step
A practical process for choosing the right connection, moving safely to digital calling and deciding whether an AI virtual receptionist genuinely improves missed-call handling.

Before you begin
This guide helps a business owner organise a first review. It does not recommend a particular provider. Availability, performance, migration and call handling must be checked against the premises and the way the business operates.
Useful principle: design the operating requirements first. A cheap or fast-looking package is not suitable if it cannot protect calls, numbers, connected equipment and essential work.
Is AI phone answering suitable for a small business?
AI phone answering can be useful when a small-business owner cannot interrupt customer work to answer each call. Review whether the service can explain opening hours, collect contact details, note the reason for a call, pass urgent matters to a real person and follow agreed procedures. Before making a decision, confirm how personal data is handled, what happens if an answer is incorrect, and how callers can reach a human when needed.

Animated overview
Eight checks before changing phone, broadband or call answering
Watch the short overview with Chris's narration and on-screen captions, then use the detailed steps below to carry out each check properly.
Read the voiceover transcript
- A phone and broadband review should start with how your business works, not with a headline speed or monthly price.
- List every line, number, user and connected device, including alarms, lifts, payment terminals and older equipment that may rely on the traditional phone network.
- Next, record what your connection must support: cloud systems, calls, video meetings, payments, remote working and the impact of an outage.
- Compare the services actually available at your address, using the written speed estimate, upload performance, support and installation plan.
- Protect your business numbers. Agree the porting process and never cancel the old line until the transfer and testing are complete.
- If missed calls are a problem, an AI virtual receptionist can capture details, book, route or take a message - but only within rules your business has approved.
- Check privacy, security, human escalation, proof-of-address requirements and the complete contract commitment before relying on the service.
- Finally, compare the whole cost and test calls, broadband, backup routes and every connected device before signing off. SME Sorted can help you review the options free of charge.
Preparation
Build a complete service inventory
Use bills, sockets, equipment labels and support records to find every service, including rarely used backup lines and separate equipment agreements.
- Recent phone and broadband bills for every account and site
- Current agreements, minimum terms, notice dates and renewal terms
- A list of telephone numbers, users, hunt groups and published numbers
- Broadband speed tests and examples of recurring faults or weak coverage
- Details of alarms, lifts, payment terminals, door systems, fax or monitoring equipment
- Your busiest call periods, missed-call pattern and out-of-hours requirements
- The business privacy notice, booking process and approved call-handling rules
Do not cancel an existing line before number-porting and migration arrangements are confirmed in writing.
Requirements
Translate daily work into measurable needs
Record the users, cloud applications, calls, video meetings, payments, remote working and customer journeys that the service must support. Then decide the consequence of an outage.
Workload
Users, cloud systems, backups, large transfers, video and simultaneous calls.
Continuity
What must keep working during a power, broadband, router or provider failure?
Customer contact
When calls arrive, where they should go and how quickly the business must respond.
Connectivity
Compare what is available at the premises
ADSL, SoGEA, FTTC, FTTP, leased lines and mobile backup serve different needs. Compare the exact product, written speed estimate, upload, latency, support, installation route and resilience rather than relying on a technology-level maximum.
Cloud access, browsing, streaming and receiving files.
Backups, cloud sync, video and sending large files.
Backup route, equipment power and fault response.
Guide speeds are not a promise. Retain the personalised estimate and contractual information supplied for the address.
Digital calling
Protect numbers, routes and essential calls
Confirm every number and range to retain, who manages the port, the planned date, call groups, opening hours, diversions, caller ID, handsets, apps and fault support.
Numbers
Published numbers, direct dials, hunt groups and outbound caller ID.
Users
Desk phones, mobile apps, softphones, headsets and remote workers.
Failure route
Call diversion, mobile alternative and the equipment that needs backup power.
Never cancel first. Closing the old service prematurely can disrupt number porting and linked services.
PSTN migration
Find and test every legacy dependency
The UK's traditional phone network is being retired. GOV.UK advises businesses to check infrastructure and devices that may rely on PSTN or ISDN, including analogue phones, alarms, payment terminals, lifts, intercoms and broadband services.
A plug fitting is not proof of compatibility. Obtain written confirmation from the equipment supplier and complete a witnessed live test before sign-off.
AI call answering
Define the rules before the first live call
An AI virtual receptionist can answer when staff are busy or unavailable, capture caller details and follow agreed booking, routing, escalation or message-taking rules. Begin with a narrow call flow and retain a human fallback.
Permitted actions
Specify what may be answered, booked, routed or recorded - and what must never be promised.
Human escalation
Urgent, sensitive, unclear or unrecognised enquiries need a clear handover route.
Privacy and security
Check caller information, transparency, recordings, retention, access and provider security.
Where a UK business number is being provisioned, expect business-verification and proof-of-address checks. Use the provider's secure process and retain only what is needed.
Whole commitment
Compare the complete cost, service and contract
Use the same operating specification and time period for every option. Add connectivity, voice users, hardware, installation, support, backup, usage, AI call handling, migration and likely exit costs.
| Comparison item | What to record |
|---|---|
| Connectivity | Record the exact product, written speed estimate, upload, latency, data limits and installation lead time. |
| Digital voice | Include users, numbers, porting, call groups, apps, handsets, call usage and support. |
| Resilience | Add backup connectivity, batteries, diversion, replacement equipment and fault-response commitments. |
| Legacy devices | Include required alarm, lift, payment, entry, fax or monitoring upgrades and testing. |
| AI call answering | Compare call volume, permitted actions, setup, support, privacy, retention and human escalation. |
| Commitment | Check every minimum term, renewal, notice, price-change and early-termination provision. |
| Implementation | Include installation, number porting, staff training, data setup and any parallel-running period. |
- The address-level availability and written speed estimate are retained.
- Every number, user, call route and connected device is accounted for.
- Number porting is agreed before the old service is cancelled.
- Power and connectivity failures have a tested response.
- The AI greeting, questions, limits, escalation and summaries are approved.
- Privacy, security, retention and proof-of-address handling are clear.
- Whole cost, contract term, price changes, notice, renewal and exit are understood.
- Installation, testing, sign-off and rollback responsibilities are assigned.
Current AI receptionist commitment: check the 18-month agreement and 90-day cancellation window against the final provider terms before proceeding.
