We're rolling out the 3CX Click2Dial browser extension (Chrome/Edge) to our users and running into a problem with over-detection.
Setup
Problem
On certain websites, the extension is turning every number on the page into a clickable dial link — order numbers, IDs, dates, etc. — not just actual phone numbers. When a user clicks any of those numbers, it tries to place a call.
Constraint
I can't just exclude the whole site, because legitimate phone numbers live on the same URL(s) as the false positives. So a domain-level exclusion / "disable on this site" would kill the numbers we actually want to dial.
What I'm looking for
The per-extension options seem limited, and it feels like some detection controls are missing. My questions:
Setup
- 3CX V20 (self-hosted), Web Client / PWA
- Click2Dial extension configured with Web URL = https://<our-fqdn>
- Users dial from the web client (no desktop app / TAPI)

What I'm looking for
The per-extension options seem limited, and it feels like some detection controls are missing. My questions:
- Are there any Admin Console / server-side settings in 3CX that control Click2Dial number-detection behavior (e.g., what qualifies as a phone number, minimum digit length, detection on/off) — pushed down to clients rather than set per-browser?
- Is there a way to make detection stricter (e.g., only match tel: links or properly formatted numbers) instead of scanning all page text?
- If this can only be managed at the extension level, what's the recommended approach for a site that mixes real phone numbers with lots of other numeric data on the same page? Is select-to-dial (manual highlight, auto-detection off) the intended fallback?
