The Static Test: Nine Questions to Ask Before You Sign Any Business Phone Contract

Ask a business owner what their phone contract says about service level guarantees and you will usually be met with a shrug. Ask the same owner what happens if the provider misses those guarantees, and the shrug deepens. This is not carelessness; it is the natural consequence of a sales process designed to conclude quickly, with the paperwork following afterwards.

The remedy is preparation. Before you sit down with any telecoms supplier — whether a household name or a regional reseller — arrive with a set of questions that cannot be deflected by a brochure. We call it the static test: if a provider squirms, hesitates or reaches for 'that's covered in the terms and conditions', you have learned something valuable before spending a penny.

Question One: Who Owns Our Phone Numbers?

This is the single most important question, and the one most frequently answered badly. Your telephone numbers — particularly geographic 01 or 02 numbers that appear on your website, vans and business cards — should be hosted in your name or, at minimum, portable to another provider without penalty.

Some providers register numbers in their own name, which effectively means you are renting your business identity from them. If you later wish to leave, the porting process can become a negotiation rather than a formality. We have seen firms held to ransom over numbers they assumed were theirs. Insist on written confirmation of number ownership and portability terms before proceeding.

Question Two: What Exactly Does the Service Level Agreement Promise?

An SLA that promises 'best endeavours' is not a service level agreement; it is a polite apology in advance. A meaningful SLA specifies response times for fault reporting, restoration targets measured in hours rather than days, and — crucially — what compensation applies when those targets are missed.

Ask for the figures in writing: mean time to restore, fault acknowledgement windows, and whether credits are automatic or require you to claim them. A provider confident in its infrastructure will volunteer these numbers. One that isn't will change the subject.

Question Three: What Happens When the Internet Line Goes Down?

If you are moving to VoIP — and with the PSTN switch-off, most businesses are — your phone system is only as resilient as your broadband. A thorough provider will discuss failover options: a secondary line, automatic call forwarding to mobiles, or a hosted system that keeps working even if the office doesn't.

If the answer to 'what happens during an outage?' is a shrug, the provider has not thought about continuity on your behalf. That is your job being done badly by someone else.

Question Four: Are There Exit Fees, and When Do They Apply?

Contracts typically run 12, 24 or 36 months, and the difference matters enormously. A 36-month term can look cheaper per month while locking you into technology that may be outdated within two years.

More important is what happens at the end. Some contracts auto-renew into rolling terms with punitive notice periods — sometimes 90 days — meaning you can be trapped for another year simply by missing a cancellation window in the small print. Ask for the notice period in writing, and diarise it the day you sign.

Question Five: What Is the Total Annual Cost, Including Everything?

Headline rates rarely survive contact with the invoice. Ask specifically about: line rental versus call charges; per-user licensing for hosted systems; handset costs or leasing; installation and migration fees; call recording, if you need it; and charges for administration changes such as adding a user mid-term.

A reputable provider will produce a single annual figure covering the realistic total. If they cannot, the omissions are doing the talking.

Question Six: Who Actually Provides the Service?

The UK telecoms market has layers. The brand you negotiate with may be a reseller sitting on top of a wholesale network, which in turn relies on an underlying carrier. Each layer can introduce a delay when things go wrong.

Ask who owns the network, who fields your fault calls, and whether support is UK-based and in-house. There is nothing wrong with resellers per se — some offer excellent service — but you deserve to know the chain of responsibility before you are depending on it.

Question Seven: How Will Migration Be Handled?

Moving phone systems carries real risk: ported numbers going dark, feature loss, staff confusion. Ask for a named migration plan with dates, a commitment to number porting timelines, and what contingency exists if the port fails. A provider who cannot describe this process in detail has either not done it often or not done it well.

Question Eight: What Support Exists Outside Office Hours?

Your customers do not only call between nine and five, and your phone system does not only fail between them. Establish exactly what out-of-hours support looks like: is it a genuine engineering escalation or an answerphone? Is it included or charged? For businesses trading evenings and weekends, this question alone can decide the contract.

Question Nine: Can I Speak to Three Existing Customers?

References are the cheapest due diligence available. Any provider serving businesses for more than a couple of years should be able to connect you with customers of a similar size and sector. Ask those customers one question: 'What happened the last time something went wrong?' The answer tells you more than any pitch.

Take This With You

Print these nine questions and take them to every meeting. The purpose is not to catch providers out — most will welcome a buyer who knows what they want. The purpose is to shift the conversation from headline prices to operational reality, where contracts are won or lost in practice.

The best deals in business telecoms are rarely the loudest ones. They are the ones where every question on this list receives a straight answer, in writing, without hesitation.
