Built by people who buy the ads too
We're a UK software company that runs marketing for law firms — so we built the call tracking product we couldn't buy, and we run our own phone lines on it.
Last updated: 8 September 2026
Who we are
CallTrace is built by Zayn Productions Ltd, a UK software company registered in England and Wales under company number 16892199, with its registered office at 1 Alvin Street, Gloucester GL1 3EJ. We build practical software for UK professional services firms — including DocsCheck for immigration advisers and SalesHub Cloud, a CRM built for legal practices.
We are small on purpose. When you ring CallTrace you get the people who build it, not a support tier and not an offshore call centre. We handle your setup ourselves, and when something breaks we fix it rather than sending you a help article.
Who runs it
Mohammed Kazi is Commercial Director, Zayn Productions Ltd and the person responsible for what CallTrace claims it does. He has spent over thirty years in sales leadership and commercial management across SaaS, legal services, hospitality and retail, including running contact-centre and phone-based sales teams — which is the specific experience CallTrace is built out of.
That matters for a product like this one. Most call tracking is designed by people who have read about phone sales. The scoring criteria, the coaching prompts and the callback timings in CallTrace come from having actually sat on the other side of those calls, and from running the advertising that paid for them.
Why CallTrace exists
Here’s why CallTrace exists: we run marketing for law firms ourselves. We watched firms spend thousands of pounds a month on Google Ads, then miss the calls those ads produced — or answer them without ever knowing which keyword paid for the case. The tools out there were American, priced in dollars, and they stopped at reporting. Nobody rang the lead back. Nobody coached the person answering the phone.
The gap was never really measurement. It was speed. Harvard Business Review’s widely cited 2011 study of lead response found firms making contact within an hour were roughly seven times more likely to have a meaningful qualifying conversation than those waiting even two hours — and in legal, where the caller has a hearing date or a letter in their hand, the window is shorter still. Every firm we worked with believed they rang new enquiries back quickly. The call logs said otherwise, more or less every time.
So we built the tool we actually wanted. Call tracking that doesn’t stop at counting calls. It rings your enquiries back in seconds, scores every conversation, coaches your team, and shows you — in pounds — which keywords are turning into paying cases.
We use it ourselves
We use CallTrace on our own phone lines every day. When you ring us, your call is tracked, transcribed and scored by the exact same system we sell you — same greeting, same scoring, same coaching notes going to whoever picked up.
That is also why the demo is the product rather than a slide deck. Put your number into the form on the homepage and CallTrace rings you back within seconds. Whatever you think of the sales pitch, you will have seen the thing work on your own phone before anyone asks you for a card.
Where we are and who we serve
CallTrace is a UK product for UK businesses. Numbers, support, billing and data handling are all domestic, prices are in pounds, and the compliance model is built around UK GDPR, the Data Protection Act 2018 and ICO guidance rather than retrofitted from a US platform.
The firms that get most out of it sell over the phone and pay for the traffic that produces those calls: solicitors and barristers’ chambers, clinics and dental practices, garages and trades, estate agents, and the marketing agencies running campaigns on their behalf. Agencies run every client from one dashboard, with separate numbers, scoring and logins per firm.
