iOS Tip 143 - Initiate Calls From Your Calendar

Let’s say you’re setting up a lunch with a contractor, and you want to make it easy to call them when your iPhone alerts you to the meeting. Or perhaps you want to embed conference call details into an event. A little-known fact about the Calendar app is that you can enter phone numbers into the Location field, and when you’re viewing the event later, you can tap the number to dial it directly (if you need a real location in the Location field, use the Notes field for the phone number instead). To add a meeting code to a conference call number, append a semicolon, the meeting code, and the pound symbol—after the iPhone dials the phone number, you can press a button to dial the code at the right moment. The entire thing would look like 518-555-0101;123456#. For a more automated, but potentially error-prone approach, replace the semicolon with one or more commas, each of which causes the iPhone to pause for 2 seconds before dialing the rest of the numbers.
