You can not send a CANCEL to cancel REFER. You can send another REFER with method CANCEL/BYE in Refer-To header to terminate the dialog created as a result of initial REFER. That also needs you to know the dialog identifiers of that dialog that you want to cancel or bye. You can get that by subscribing to "dialog" event package.
