Seven Straight Answers Before You Retire the Desk Phone

Ask three providers to explain VoIP and you will get three different clouds of jargon. Strip the terminology away and the concept is simple: your calls travel over your internet connection instead of a phone line. The complexity — and the risk of an expensive mistake — lies in the details. Here are the seven questions worth asking before you sign anything.

1. What Will Call Quality Actually Be Like on Our Connection?

VoIP quality is only as good as the broadband beneath it. A provider worth their contract will ask about your connection before quoting. If you have full fibre, calls will typically sound better than traditional lines. On a strained ADSL connection, expect jitter and dropouts at busy times. Any provider who promises flawless calls without first asking about your bandwidth is telling you what you want to hear.

2. Can We Keep Our Existing Numbers?

For most businesses, the phone number is the asset. Porting UK numbers to a VoIP platform is routine, but it takes time — typically a few weeks — and must be handled correctly or you risk a gap in service. Ask the provider to manage the port end-to-end, confirm it in writing, and never cancel your old line until the port is complete.

3. What Is the True Monthly Cost Per User?

Headline prices often exclude the extras. Before comparing quotes, itemise:

• Line rental and per-minute charges beyond any inclusive allowance
• Handset costs or hardware leasing
• Setup and installation fees
• Charges for features such as call recording, auto-attendants or CRM integration
• VAT — many advertised prices exclude it

A £10-per-user headline can become £25 once the essentials are added.

4. What Happens When the Internet Goes Down?

A landline keeps working in a power cut; a VoIP handset does not. Ask how the provider handles failover — can calls be automatically rerouted to mobiles, and can staff log in from home or a laptop? For most SMEs, this flexibility is one of VoIP's genuine advantages, but only if it is configured before the outage, not during one.

5. Are Emergency Calls Handled Properly?

Under UK regulations, providers must support 999 calls and share your location with emergency services. If your team works across multiple sites or from home, confirm how location information is kept current. It is an unglamorous question that separates established providers from resellers.

6. What Do the Contracts and Exit Terms Look Like?

Some VoIP contracts run for three years with automatic renewal and substantial early-termination fees. Others are monthly rolling. Understand which you are signing, what happens to your numbers if you leave, and whether handsets you bought remain yours. Portability of your numbers is your leverage — protect it.

7. How Good Is the Support When It Matters?

A phone system is critical infrastructure. Ask whether support is UK-based, what the response commitments are, and whether you will speak to engineers or a script-reading call centre. Where possible, speak to existing customers of a similar size before committing.

The Straight-Talk Standard

At Lightspeed Communications, we built our approach around these questions because we were tired of watching small businesses overpay for systems they did not understand. A good VoIP provider should explain the trade-offs plainly, quote honestly, and treat your phone number with the respect it deserves. If a prospective supplier cannot answer these seven questions clearly, that silence is your answer.
