Call attribution · powered by your 3CX

Know which campaign
made the phone ring.

Zen Call Attribution links every inbound call back to the exact campaign, medium and source that drove it — written automatically onto one CRM record.

Native to your existing 3CX No third-party platform No per-call charges
The blind spot

You measure every click.
Then the phone rings — and the data goes dark.

Businesses spend heavily tracking website clicks and campaign performance. But the moment a prospect picks up the phone, attribution stops. You can't see which campaign earned the call, so the spend that actually drives revenue is invisible. Zen Call Attribution closes that loop.

Without call attribution
  • Phone leads logged as “direct” or “unknown”
  • Budget shifted on incomplete data
  • Best-performing campaigns under-credited
  • Another monthly platform bill to justify
With Zen Call Attribution
  • Every call tied to its source campaign
  • Campaign + call on one CRM record
  • Spend optimised on the full picture
  • Runs on the 3CX you already pay for
How it works

From first click to closed call — on one record

Three connected layers, working quietly behind your website and phone system. No DNI platform, no per-call fees — just complete attribution where you already work.

01

Capture the click

A lightweight snippet on your site reads the campaign's UTM tags and shows each visitor a unique number from your pool — recording the source at the moment of click.

02

Connect the call

The visitor calls that number. It routes straight into your existing 3CX — no new SIP trunk, no third-party line — passing the call detail to the platform.

03

Complete the record

We match the call to the session and write the campaign source and full call detail onto a single contact record in your CRM, automatically.

Matching uses caller number first, then session timing — with the campaign source kept on the record either way.
Why Zen

Attribution that lives where you already work

Most call-tracking tools bolt a third-party platform onto your telephony, with their own SIP trunk and per-call charges. Zen Call Attribution runs through the 3CX system we already support — managed from your own Zen portal, with complete data and a single partner for the whole stack.

Pricing
