What is Call Return?

Call Return is part of your voicemail service that means you can quickly call people back who've left you a message just by pressing the # key.

How does it work?

  • As long as your voicemail captured the caller's phone number, you'll be able to use Call Return by pressing # on your phone.
  • When you listen to your voicemail menu to pick up your messages, it'll give you the option to use Call Return.
  • If the caller withheld their number or they were calling from a number that cannot be ‘Call Returned', then Call Return won't be available.

How much will it cost?

  • The actual service doesn't cost anything in itself. It's just part of your voicemail service
  • The call that you make using Call Return will be charged as a normal call within your inclusive minutes or from any allowances that you may have within your price plan. 
  • Call Return will work for international and premium numbers (if your voicemail captures their numbers) if they are part of your price plan. 
  • You'll see your Call Return calls on your bill as ‘Call Return'.


  • Call Return will only work if your voicemail has captured the incoming number.
  • It will not be available if the caller withheld their number or called you from a line that doesn't display its number.

Although you can press # at any time while you're listening to your voicemail menu, it will only work if Call Return is available.
