Many of our contacts has more than one phone number under their contact cards. Sometimes we do instant calls from recent numbers. During the dial process I am curious which number I have been dialed. IPhone shows only work-mobile or whatever.. However sometimes we just don't really pay attention if mobile number is really recorded under work number or not.. So it would be very helpful for me to see what exact number I am dialing during the process of calling.. (both while dialing and talking). It might be the case I can even cancel my call right after my initiation if the number is not the one I wanted to call.. Please do not come up to me solutions like: 'be careful/smart before you dial' 'double check before dial' 'better organize your contacts' I would like to have the flexibility to see which number exactly I am dialing, that's all, rest is my actions to carry on with that..
