VoIP and Web Integration: Click-to-Call for Businesses
Last updated: March 2026 · Reading time: 3 minutes
Phone numbers on websites that aren't clickable create friction. On mobile devices, users have to type the number. On desktop, the call doesn't happen because the effort is too high. Click-to-call eliminates this media break.
Implementing Click-to-Call Correctly
The technical implementation is simple: tel: links in HTML. The strategic implementation requires more thought.
Phone numbers belong in the header, on contact pages and in CTAs. The tel: protocol is supported by all modern browsers and operating systems.
For conversion tracking, clicks on tel: links are captured as events in analytics. This tells you which pages generate calls so you can optimize your marketing accordingly.
VoIP and CRM Integration
Modern VoIP systems can be connected with CRM platforms. Incoming calls are automatically assigned to a CRM contact. The sales team sees the customer history when the phone rings.
Drupal can serve as the connecting link: the website generates the lead, click-to-call initiates the call, and the CRM logs the conversation. A closed chain from the first click to closing the deal.

Does click-to-call work on all devices?
Yes. On mobile devices, the call starts directly. On desktop devices, the configured telephony app opens (Skype, Teams, FaceTime or the company's VoIP software).
Can click-to-call clicks be tracked?
Yes. Clicks on tel: links can be captured as events in Google Analytics or Matomo. This way you measure which pages and CTAs generate the most calls.
