So kids, in the olden days you had to make a “phone call” from a device like this. No it didn't have Facebook.
There are a number of easier ways to make phone calls on your Mac, one of which is a utility called Continuity Keypad. There's also just opening Contacts and clicking on the phone handset by the phone number, which is effective but not very exciting. Or fun. So here's how to have some fun with it!
You can use something called a “URL scheme” which is the same idea that allows apps on iOS to “link” to other apps. Marshall Huss outlines a few ways to dial using URL schemes on his site, including using the address bar in Safari:
tel://18007672775<phone number="“18007672775" "="">
You can also type
open tel://17192662837
in Terminal and get the same result. Using Alfred you can type the same thing and get a phone call. But as Marshall points out, you may not carry any phone numbers in your brain anymore, so he offers a workflow for Alfred and outlines how to configure it. Perhaps now if you have to make one of those old-timey phone calls, it's slightly less drudgery. Or you can just put these in your Bag Of Tricks and pull them out to show off.
