When in a call, you can transfer the caller to another contact or number using the transfer icon in the dial pad panel. Once selected, you can choose from a Blind or Attended transfer.
Blind transfers will transfer the call to the recipient and the call will be ended for you.
Attended transfers will transfer the call to the recipient but will allow you to speak to the user prior to transferring the call. You will also have the option to cancel the transfer and return to the original call if required.
