cisco 7960 - dialing/transfer - stored numbers

forgive me if this has been asked before, I googled and searched first w/o luck

I have a deployment with the Trixbox 2.6.2 with Cisco 7960 phones. If I attempt to dial a number or transfer to number beginning with a number that is already stored in the phone, I have to navigate to the clear selection (so to dial the correct ext or phone number).

Is there a way to turn off the stored numbers?
