I am a new employee here and apparently you can transfer a call to an outside line (i.e. someone calls and the person they're looking for aren't here and asked to be patched through to that person's cell phone...). Can anyone help me out? I know that you have to use the flash button, but not sure how... For example, needed to patch someone through to another perons's cell # that is on speed dial. Thanks in advance if anyone can help me.
