If a mobile click-to-call button has no tel: link, tapping it opens the dialer with the original hardcoded number instead of the swapped Invoca number.
Symptoms
- The Invoca Tag is running on the website, and the number swaps as intended on both mobile and desktop.
- The issue is isolated to mobile devices: the number rotates correctly on the page, but when a visitor taps the click-to-call button, the dialer displays the original hardcoded number instead.
Cause
Most sites include atel: link behind a click-to-call button on mobile, which the Invoca Tag detects and updates as it runs. In this case, the button had no tel: link for the Tag to reference, so tapping it opened the dialer with the original hardcoded number rather than the swapped one.
Resolution
Update the website, or ask a web developer to update the button, to include atel: link for the hardcoded number.
