Dial extensions by pausing, then entering the number

To reach an extension on an iPhone, use the pause feature built into the Phone app. When you call a business or organization with a main number and extension, add a pause and the extension digits to the contact. The pause gives the automated system time to process the main number before sending the extension.

The simplest method is to save the full dialing sequence in your contacts. When you call that number again, the pause happens automatically and the extension dials without you having to do anything.

Key Takeaways

  • Add a pause followed by the extension number when saving a contact, and iPhone will automatically pause and dial the extension on future calls.
  • Use the asterisk key to create a pause in the Phone app's keypad — hold it down until a comma appears in the number field.
  • A comma creates a 2-second pause; if you need more time, add multiple commas or use the wait feature (semicolon) to pause until you manually continue.
  • You can also dial extensions manually by waiting for the automated system to finish, then tapping the keypad and entering the extension digits.

Save extensions in your contacts for automatic dialing

Open the Phone app and tap Contacts. Find or create the contact for the business or organization. Tap Edit, then tap the phone number field. Position your cursor after the main number where you want the pause to occur.

Hold down the asterisk (*) key until a comma appears in the number field. This comma represents a 2-second pause. After the comma, type the extension number. For example, if the main number is 555-123-4567 and the extension is 890, the field should read: 555-123-4567,890. Tap Done to save.

The next time you call this contact, iPhone automatically pauses for 2 seconds after dialing the main number, then sends the extension digits. You do not need to do anything — the phone handles it.

Add multiple pauses if the system needs more time

Some automated systems take longer to process the main number before they are ready for an extension. If the extension does not dial on the first try, you can add extra pauses by inserting multiple commas.

Edit the contact again and add another comma before the extension. For example: 555-123-4567,,890 creates two 2-second pauses (4 seconds total) before the extension dials. Test the number by calling it, and adjust the number of commas until the timing works reliably.

Use the wait feature to pause until you manually continue

If you want more control, use the wait feature instead of a pause. Hold down the asterisk key longer — past the comma — until a semicolon (;) appears. This semicolon tells iPhone to pause and wait for you to manually tap a button before continuing.

For example: 555-123-4567;890 will dial the main number, pause, and display a "Continue" button on your screen. When you see the automated system is ready, tap Continue and the extension dials. This is useful when you are not sure how long the system will take or when you need to listen to menu options before entering the extension.

Dial extensions manually if you do not want to save them

If you are calling a number you do not plan to use again, you can dial the extension manually without editing your contacts. Dial the main number normally and wait for the automated system to finish its greeting or menu.

Once you hear the prompt for an extension, tap the keypad icon at the bottom of the call screen to bring up the number pad. Tap the extension digits. The system will process them just as if you had entered them during the initial call.

Troubleshoot if the extension does not dial

If you saved a contact with a pause and the extension still does not dial, the pause may be too short. Edit the contact and add more commas to increase the wait time. Some systems need 4 to 6 seconds before they are ready to receive an extension.

Another common issue is that the extension may require a different input method — some systems ask you to press a key like # or * before entering the extension. If that is the case, add those characters after the pause. For example: 555-123-4567,#890 will pause, then send a # symbol, then the extension.

If the automated system is very slow or unpredictable, use the wait feature (semicolon) instead of a pause. This lets you listen and tap Continue when you are certain the system is ready.

Frequently Asked Questions

Can I dial an extension without saving it to a contact?

Yes. Call the main number, wait for the system to finish, then tap the keypad icon at the bottom of the screen and enter the extension digits manually. This works for one-time calls but requires you to be present during the call.

What is the difference between a comma and a semicolon?

A comma creates an automatic 2-second pause. A semicolon pauses and waits for you to tap a Continue button before the next digits dial. Use a comma for predictable systems and a semicolon when you need to listen first.

How many commas should I add?

Start with one comma (2 seconds). If the extension does not dial, edit the contact and add another comma. Most systems work with two or three commas (4 to 6 seconds total). Test and adjust based on what works.

Does this work with all phone systems?

It works with most automated phone systems that accept touch-tone input. Some older systems or live receptionists may not respond to dialed extensions. If the extension does not work after multiple attempts, call and ask the receptionist for the correct dialing method.
