Sometimes you want a phone number to be linked, so you can call directly by clicking on it (especially when viewing the website on a mobile device).
To do this, write the number as you wish it to be displayed on the web, and then mark it and create a link. (4.7.1)
After marking the text and clicking the Insert link icon, select the 'External URL' tab and write tel: and then a number (1).
NOTE! There should be no space or dashes in the number. Including the country code, is also suggested.
At the end apply with 'Set link' (2). (4.7.2)
