How to Dial an Extension on Android?

To dial an extension on your Android device, you have two convenient methods to choose from:

Method 1: Using the Asterisk (*) Key

  1. Launch the Phone app on your Android device.
  2. Enter the primary phone number you wish to call.
  3. To enter the extension, long-tap the asterisk (*) key on your phone’s keypad until a comma appears. This comma acts as a pause.
  4. After the comma, type in the extension number.
  5. Finally, tap the “Call” icon to initiate the call. Your Android device will dial the primary number and then automatically dial the extension after a short pause.

Method 2: Using the Pound (#) Key

  1. Open the Phone app on your Android device.
  2. Enter the primary phone number you want to call.
  3. Instead of using a comma as in the first method, you can use a semicolon (;) by long-tapping the pound (#) key on your phone’s keypad.
  4. After adding the semicolon, type in the extension number.
  5. Tap the “Call” icon, and your Android device will dial the primary number, pause briefly, and then automatically dial the extension.

Both of these methods are practical and efficient ways to dial an extension on your Android device, giving you the flexibility to choose the one that suits your preference or the specific requirements of the phone system you are using.

How do you Call an Extension on Android?

To call an extension on an Android device, open the Phone app, dial the main number, insert a pause (,) or a wait (;), type the extension, and then tap the “Call” button. Your Android device will dial the primary number and connect to the extension automatically.

How To Add an Extension to a Saved Contact on an Android Device?

To add an extension to a saved contact on an Android device, follow these steps:

  1. Open Contacts: Open your Contacts app on your Android device.
  2. Find the Contact: Locate the contact you want to add an extension to in your contact list.
  3. Edit the Contact: Tap on the contact to open their details. Look for an “Edit” or “Pencil” icon (it may vary depending on your phone’s interface), and tap on it.
  4. Add the Extension: In the contact’s details, you should see an option to add additional numbers or details. You can typically find a “Phone” field. Add the main phone number and then, following the number, add a comma (,) for a pause or a semicolon (;) for a wait, followed by the extension number.
  5. For example, if the main number is (555) 123-4567 and the extension is 1234, you can add it as: (555) 123-4567,1234 for a pause or (555) 123-4567;1234 for a wait.
  6. Save the Contact: After adding the extension, save the contact by tapping the “Save” or “Checkmark” icon.

Now, when you call this contact from your Android device, it will automatically dial the extension as you’ve saved it in their contact details.
