Whilst on a call, press the Phone or Contacts icon in the top-left of the screen to locate the contact you want to transfer to.
Select the number or extension you want to transfer the call to from their contact details. This will automatically put the caller you’ve been speaking to on hold. You can also use the keypad to type in a number if they are not a saved contact.
To transfer, call the contact you want to transfer the call to. Once you have connected to the contact, press the transfer button and the two calls will be connected. A message will appear to tell you the calls have been connected.
