The basic method: pause, then the extension number

To dial a phone extension on iPhone, call the main number first, then use the pause feature to automatically send the extension digits after the call connects. Open the Phone app, tap the keypad icon, and enter the main number. Before you call, tap the + symbol (or * if you're already in a number field) to add a pause, then type the extension number. When you call, iPhone will dial the main number, wait for the system to answer, then automatically send the extension.

The pause gives the phone system time to answer and prompt you for an extension. Without it, iPhone sends the digits too quickly and the system won't recognize them. A standard pause lasts about two seconds, which works for most business phone systems.

Key Takeaways

  • Use the pause feature (accessed by tapping + or * in the keypad) to insert a delay before the extension digits.
  • The format is the main number, then pause, then the extension — for example, 555-123-4567,123 (the comma represents the pause).
  • If the system doesn't recognize the extension, you can manually send the digits by tapping them on the keypad after the call connects.
  • Some phone systems use a wait feature instead of pause; if the extension doesn't go through, try using a semicolon (;) instead of a comma.

Step-by-step: Adding a pause to a phone number

Open the Phone app and tap the keypad icon at the bottom. Type the main phone number you're calling. Now tap and hold the * key until a + symbol appears (or if you see the + already, just tap it). A menu will show options including "pause" — tap that option.

After you select pause, a comma will appear in the number field after the main number. Now type the extension digits. The full number should look like this: 555-123-4567,123 (where 123 is the extension). Tap the green call button to dial. When the main number answers, iPhone will automatically send the extension after the two-second pause.

When to use wait instead of pause

Some automated phone systems need more time than a standard pause provides, or they require you to press a key before accepting the extension. If the pause method doesn't work, try using a wait feature instead. In the same menu where you found pause, select "wait" — this will insert a semicolon (;) instead of a comma.

With wait, iPhone will pause and then wait for you to manually tap a key on the keypad to send the extension. This is useful if the system says "press any key to continue" before it's ready for the extension number. You'll see a prompt on the screen asking if you want to send the digits; tap "send" when you're ready.

Saving extensions in your contacts

If you call the same extension regularly, save it in your contacts so you don't have to add the pause every time. Open Contacts, find or create the person's entry, and tap "edit." In the phone number field, enter the full number with the pause: 555-123-4567,123. Tap "done" to save.

Now when you call that contact, iPhone will automatically dial the main number and send the extension without any extra steps. This works for department extensions too — you can create a contact for "Company Name - Sales" with the main number and sales extension built in.

Manually sending the extension if automatic doesn't work

If you dial the number and the extension doesn't go through automatically, you can send it manually. After the main number answers, look at your iPhone screen — you'll see the keypad icon at the bottom. Tap it to reveal the number pad, then tap the extension digits one at a time. The system will receive them just as if you'd typed them on a regular phone.

This is also useful if you're not sure whether the system is ready for the extension yet. Some systems play a greeting or menu before they're ready to accept extensions, so waiting a few seconds and then manually entering the digits gives you more control.

Troubleshooting: Extension not going through

If the extension isn't connecting you to the right department or person, the pause might be too short. Try editing the contact and adding another pause — change the comma to a comma followed by another comma (,,) to create a longer delay. Some systems need three to four seconds instead of two.

Another common issue is that the system might use a different prompt method. If you hear "press 1 for sales, press 2 for support," you're not dealing with an extension system — you need to press the number during the menu, not after. In that case, don't use a pause at all; just tap the number when you hear the prompt.

Frequently Asked Questions

What's the difference between pause and wait?

Pause automatically sends the digits after two seconds. Wait pauses and then asks you to manually tap "send" before the digits go through. Use pause for most business extensions; use wait if the system needs you to press a key first or if you want to control the timing yourself.

Can I add multiple pauses to one number?

Yes. If you need to navigate a phone menu before entering an extension, you can add pauses between different digit sequences. For example: 555-123-4567,1,,2,,123 would dial the main number, pause, send 1, pause, send 2, pause, then send 123. Each comma is a separate two-second pause.

Will the pause work if I'm calling from a different country?

Yes, the pause feature works the same way regardless of where you're calling from. The pause is handled by your iPhone before the call reaches the phone system, so international calls work just like local ones.

What if the extension is a letter or symbol, not a number?

Most phone systems use numbers only. If you're told an extension is a letter (like "press A for accounting"), you'll need to press the number key that corresponds to that letter on the phone keypad — A is on the 2 key, B and C are on the 2 key, and so on. Check your phone's keypad to see which numbers map to which letters.
