From CUCM 3.3 you can prefix the leading 0 and the trunk access code if you desire, so that when you receive a call or miss a call you can simply go to your directories and press the dial softkey without having to key in the full number.
This is configured within the CallManager Service service Parameters. Open the advanced settings and scroll to the
Cluster Wide Parameters for Device - Phone section or Device - MGCP Gateway.

For example, if you call from your mobile and numplan is unknown then if there is a prefix configured, it is this which will prefixed to the calling party number.
