Dialing an extension on iPhone
When you call a business number on your iPhone and hear an automated menu asking you to press a number for an extension, you have three ways to send that tone: pause and wait for the prompt, use the keypad during the call, or add the extension to your contact ahead of time. The simplest method depends on whether you're calling the same number repeatedly or making a one-time call.
The most common situation is calling a main number and hearing "Press 1 for sales, press 2 for support." You can tap the numbers on your keypad while the call is active, just as you would on any phone. If you need to wait for the menu to finish speaking before entering the extension, or if you want the phone to dial the extension automatically when you call back, you can save the extension directly in your contact information.
Key Takeaways
- You can press numbers on your iPhone keypad during an active call to send extension tones to a business phone system.
- Saving an extension in a contact uses a pause or wait symbol so the extension dials automatically after you call the main number.
- A pause waits two seconds before sending the extension; a wait symbol lets you confirm before the extension is sent.
- The keypad appears automatically when you call, but you may need to tap the keypad icon if it disappears during the call.
Sending an extension during an active call
When you call a business number and the automated system asks for an extension, tap the Keypad button at the bottom of your screen. The numeric keypad will appear, showing numbers 0 through 9 and the symbols * and #. Tap the number or numbers for the extension you need — for example, if you need extension 4, tap 4 once.
The tone will send when ready to the phone system on the other end. You do not need to press a "send" button or confirm anything. If you need to enter multiple digits (such as extension 42), tap each number in sequence. The system will receive them as if you had pressed them on a traditional phone keypad.
If the keypad disappears while you're on the call, tap the phone number or contact name at the top of the screen to bring it back. This is normal behavior — the keypad hides automatically after a few seconds of inactivity to keep the screen clear.
Saving an extension in a contact with a pause
If you call the same business number regularly and always need the same extension, you can save the extension in your contact so it dials automatically. Open the Contacts app and either create a new contact or edit an existing one. In the phone number field, enter the main business number, then add a pause, then add the extension digits.
To add a pause, tap the +*# button on your keyboard (visible when the number field is active), then select Pause from the menu that appears. A comma will appear in the phone number field — this represents a two-second pause. Then type the extension number. For example, a complete entry might look like: 555-123-4567,42
When you call this contact, the iPhone will dial the main number, wait two seconds for the automated system to finish its greeting, then automatically send the extension tone. This works best when you know the system always takes about two seconds to play its menu.
Using a wait symbol for manual confirmation
If the timing of the automated menu is unpredictable, or if you want to confirm before the extension is sent, use a wait symbol instead of a pause. Open the contact and tap the +*# button on your keyboard, then select Wait from the menu. A semicolon will appear in the phone number field.
When you call a contact saved with a wait symbol, the iPhone will dial the main number and then pause. A prompt will appear on your screen asking "Continue?" — tap it when you hear the system is ready for your extension input. The extension will then be sent. This method gives you control over the timing and works with systems that have longer or variable greeting times.
You can combine pauses and waits in a single contact if needed. For example, if a system requires you to wait for a greeting, then enter an extension, then enter an account number, you could save: 555-123-4567;42,1234 (wait for confirmation, send extension 42, pause two seconds, send account number 1234).
What to do if the extension doesn't send
If you tap the extension number and nothing happens, check that you are still on an active call — look at the green bar at the top of your screen showing the call duration. If the call has dropped, you will need to call again. If the call is active but the keypad is not visible, tap the phone number at the top of the screen to bring the keypad back.
If you saved an extension in a contact and it did not dial automatically, the pause or wait timing may not match the system's actual menu speed. Try calling again and manually entering the extension using the keypad instead, or edit the contact to use a wait symbol so you can control the timing yourself.
Some older business phone systems do not respond to tone input from mobile phones, though this is rare. If a system consistently does not accept your extension input, the business may require you to stay on the line and speak to a receptionist, or they may have a separate direct number for that extension that you can call instead.
Saving extensions for multiple departments
If you frequently contact different extensions at the same business, create separate contacts for each one rather than trying to save multiple extensions in a single contact. Name them clearly — for example, "Acme Corp Sales" and "Acme Corp Support" — so you can quickly find the right one when you need to call.
Alternatively, you can add multiple phone numbers to a single contact, each with its own extension saved. Open the contact, tap Edit, and tap the green plus sign next to the phone number field to add another number. Label each one (such as "Sales" or "Support") so you know which extension each number contains. When you call this contact, you can choose which number to dial from the list that appears.
Frequently Asked Questions
Can I use symbols like * or # as part of an extension?
Yes. Tap the +*# button on your keyboard to access the asterisk and pound symbols, then tap them just as you would any other digit. Some automated systems use these symbols as part of their menu navigation. Enter them in the same order the system requests.
What's the difference between a pause and a wait?
A pause automatically waits two seconds before sending the next digits, with no action needed from you. A wait pauses and shows a prompt on your screen asking "Continue?" — you tap it to send the next digits when you're ready. Use pause for predictable timing, wait for systems with variable menu lengths.
Will the extension dial if I'm using speakerphone?
Yes. Pauses and waits work the same way whether you're on speakerphone, using the receiver, or using headphones. The extension will send automatically at the right time, or the wait prompt will appear for you to confirm.
Can I edit a contact to remove an extension I saved?
Yes. Open the contact, tap Edit, and delete the pause or wait symbol and the extension digits from the phone number field. Tap Done to save the change. The next time you call, only the main number will dial.
What if I need to enter a pause between the extension and another code?
You can chain pauses and waits together. For example, if you need to dial an extension, wait for a prompt, then enter an account number, save it as: 555-123-4567,42,1234 (pause two seconds, send extension 42, pause two seconds, send account number 1234). Adjust the number of commas based on how many pauses you need.
