How to Dial an Extension on iPhone?

Step 1 – Once you open the Phone app ensure that the Keypad screen is visible.

Step 2 – Dail in the original number you wish to call and Long-press the (*) key until the phone number is followed by a comma (,).

Step 3 – Now dial the extension number after the comma. Also repeat the steps to add additional commas if you want the pause to be longer than two seconds.


Step 4 – Long-press the pound sign (#) until a semicolon (;) appears to add “wait-to-dial.”

Step 5 – Now all you need to do is hit the green call button and you are done.

A few things that you need to keep in mind.

  • Once you put ‘pause’ (,) in the phone number the phone app will pause before dialing the extension.
  • The phone app will display the extension when you enter a “wait” denoted by a semicolon (;) but won’t automatically dial it. When on a call, all you have to do is dial the “extension number” dial-up button at times when you are unsure of the exact amount of waiting time until the opportunity to input the extension appears, this is useful in some cases.
