Imagine that you’re adding a calendar event for a meeting with a contractor, and you want to make it easy to call them if you are running late. Or perhaps you want to embed conference call details into an event. Simply enter a phone number into an event's Location or Notes field in the Calendar app. Then, whenever you’re viewing the event later on your iPhone, you can tap the number to dial it directly. 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 whole 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. Finally, if you suffer from way too many conference calls, the MeetingMogul app can make dialing in even easier.
