Is the Cheapest VoIP Provider Ever Really the Cheapest?
Almost every business that moves its phones online starts with the same question: who is cheapest? It’s a reasonable place to begin. But a low headline price and a low annual bill are not always the same thing.
This article shows where the extra costs tend to hide, so you can compare SIP trunk providers and hosted telephony suppliers on what you will actually pay.
Why the Headline Price Misleads
Providers advertise the number that looks best. That might be a per-channel fee, a per-user monthly price or a low per-minute rate. Each is real, but each leaves out something.
A per-user price may exclude call charges. A per-minute rate may apply only to landlines. A generous call bundle may have limits that a busy team passes within days.
None of this is dishonest. It’s just selective, which is why a quote needs to be read line by line.
Eight Costs That Often Go Missing
Mobile calls. Many businesses make a lot of calls to mobiles, and these are frequently excluded from “unlimited” bundles or charged at higher rates.
Non-geographic numbers. Calls to 03, 084, 087 and other ranges can be billed separately.
Number rental and setup. Each number or range may carry a monthly fee, and setup charges can apply.
Porting fees. Moving existing numbers can attract a one-off charge per number or per block.
Extra channels or users. Check the price of adding capacity during a busy season, not only the starting price.
Call recording and add-ons. Recording, reporting and queue features may be extra on cheaper plans.
Hardware. IP handsets, adapters or a gateway for an older PBX can add to the first-year cost.
Early exit and price rises. Long minimum terms, auto-renewals and annual increases change the real cost over time.
How to Compare Quotes on Equal Terms
Build a simple spreadsheet and put every quote into the same rows. Then price your real usage, not an imagined average.
Take your last three phone bills and note:
- total minutes to landlines, mobiles and non-geographic numbers
- the highest number of simultaneous calls you handle
- how many numbers you hold
- any international calling
Apply each provider’s rates to those figures. Then add one-off costs and divide by the contract term to get a monthly equivalent. This is the number to compare.
When Cheap Really Is Fine
Low-cost Hosted VoIP isn’t a trap by definition. A small team with simple needs, a stable internet connection and modest call volumes can be well served by a no-frills platform.
It works best when:
- you can tolerate a slower support response
- your phones aren’t critical to revenue minute by minute
- you’re comfortable managing basic configuration yourself
- the contract is short or flexible
The risk grows as the phones become more important. A trade business that takes bookings by phone loses money on every missed call, so a modest saving can be outweighed by one bad outage.
What Cheaper Pricing Often Trades Away
Lower prices usually reflect a trade-off somewhere. Common ones include:
- Support hours and channels. Ticket-only support is cheaper to run than a phone line staffed by engineers.
- Network resilience. Fewer upstream carriers and data centres cost less but offer fewer routes around a fault.
- Number porting help. Some providers leave porting largely to you.
- Service credits. Check whether a stated uptime figure comes with compensation if it isn’t met.
Ask directly about each of these. A confident provider will answer clearly.
Examples From UK Businesses
A five-person lettings agency makes lots of mobile calls to tenants and landlords. A plan with a low per-minute rate for landlines but charged mobile calls turns out dearer than a slightly higher plan with mobiles included.
A 40-seat telesales team is price-sensitive but sees heavy peaks. The cheapest per-channel quote is outweighed by overage charges, so a bundle priced for peak usage wins.
A small accountancy practice needs reliability at tax deadlines. It chooses a mid-priced supplier with phone support because a failed week costs far more than the monthly difference.
Where Wavetel Business Fits In
Providers that focus on business communications, such as Wavetel Business, usually quote channels, numbers and calls separately, which makes comparison easier. Whichever suppliers you consider, ask each for an itemised written quote against the same brief.
Frequently Asked Questions
What is the cheapest way to move off ISDN?
It depends on your equipment. If your PBX is IP-capable, a SIP trunk keeps costs low. If it isn’t, factoring in a gateway or new system matters. Compare total first-year cost.
Are “unlimited” calling plans really unlimited?
Usually they have fair-use policies and exclusions, often for mobiles, international or non-geographic numbers. Ask for the policy in writing.
Is cloud telephony more expensive than a SIP trunk?
Not necessarily. Hosted telephony charges per user but includes the phone system, so you avoid maintaining on-site equipment. The better value depends on your size and setup.
Conclusion
The cheapest quote is only cheapest if it covers what you actually use. Itemize every cost, price your own call patterns, and weigh the trade-offs in support and resilience.
Your practical next step is to pull your last three phone bills and ask two or three providers to quote against the same figures. That comparison will show you the real price within a day.
