Use tel:******, then register a touch event for the element, and then count in the event

After the user makes the call, find a way to trigger an event and then store it in the database.

Is there any other good solution besides the above methods?

It feels like we can only judge whether the user clicked on the number, but not whether the call was actually made, because the system interface will appear after clicking on the number...
