Put the following in the EMBED CODE option of the INSERT edit function.

<a href="tel:+1-303-499-7111">Click to Call NIST Time Service!</a>

You can also use SKYPE by entering:

<a href="skype:echo123?call">Call the Skype Echo / Sound Test Service</a>

<a href="skype:SKYPE USER NAME?call">Call me on Skype</a>

The visitor must have the Skype app installed for the Skype link to work.

For the button I used this code:

View this page with your cellphone to see if it works.

You can also use Google Hangouts. Insert the URL 'hangouts.google.com'. You will be able to select to make a phone call or send a text or make a video call.

You can create a QR Code image for dialing. There are several QR Code generators, including an add-on for Chrome.
