Occam alternative

The Occam Alternative for Teams That Would Rather Trial Than Book a Demo

Occam is stronger where you need to discover an IVR you no longer understand, or load-test it. We are stronger where you already know the paths and want them watched continuously, at a price you can see before the first meeting. Most evaluations between the two come down to whether discovery is a live requirement.

Occam is a UK IVR testing specialist covering discovery and mapping, functional testing, load testing and call quality assurance, sold to enterprises and through channel partners with no published pricing.

Which one you should actually buy

Where each of us wins, including the cases where we are the wrong choice.

Choose Phone Number Monitoring if…

  • You already know which paths matter and want them watched continuously, not discovered.
  • You want to price it yourself and start today rather than book a demo to find out whether it is affordable.
  • Your estate is tens of numbers, where an enterprise agreement is out of proportion.
  • Continuous monitoring with escalation into your on-call rota is the actual requirement.
  • You want month-to-month billing.

Choose Occam if…

  • You do not know what your IVR looks like any more. Automated discovery and mapping, which means crawling an undocumented tree and producing a map of it, is a real capability of theirs and one we do not have. For an inherited estate nobody has documented in years, that is genuinely valuable and we would point you at them.
  • You need load testing. They offer it, we do not.
  • You want one vendor covering discovery, functional testing, load testing and SMS testing together.
  • You are buying through a channel partner or systems integrator who already carries them.

Occam

Not published. We found no pricing page, and the calls to action we checked led to a demo request, so there is no figure to quote and we will not estimate one.

What is observable: enterprise logos, channel distribution and a demo-first motion, which usually implies annual agreements scoped per engagement.

What we checked, and when

Everything on this page about Occam was read from public sources on September 14, 2026. Vendors change their sites; where a claim here no longer matches what you find, theirs is current and ours is stale. Tell us and we will correct it.

  • Their site navigation and footer, checked for a pricing page.
  • Their product pages for discovery, mapping, functional testing and load testing.
  • A third-party directory listing that mentions a free trial. See below.

What we could not confirm

  • Whether a free trial exists. A directory lists one; nothing on their own site offers one. Ask them.
  • Contract pricing, which they do not publish.

Where this page says a competitor does not have something, it means we could not find it published, not that we have proof it does not exist. Where we have direct evidence, the page says so explicitly.

Frequently asked questions

What does Occam do that you do not?
Two things, clearly. Automated IVR discovery and mapping, which means pointing a tool at a menu tree nobody has documented and getting a map back, is a developed capability of theirs and we have no equivalent; you tell us which paths to test. And load testing, which we do not offer at all. If either is your requirement, they are the better buy.
What do you do that they do not?
Publish a price and let you start without talking to anyone. That is the main practical difference in an evaluation. Beyond that we are narrower and cheaper: continuous production monitoring with escalation, priced per line and per call, month to month.
Do they offer a free trial?
We cannot confirm it. One third-party directory lists a free trial, but nothing on their own site offers one and every route we could find leads to a demo request. We have flagged that rather than resolve it in our favour. Ask them directly.
Is discovery worth paying extra for?
It depends entirely on whether you know your own call flows. If you inherited an estate nobody has documented, discovery turns an unknown into a testable map and is worth real money. If your team designed the IVR and can list the branches from memory, you would be paying for a one-off exercise you could do by hand in an afternoon, and you would still need something to monitor it continuously.
