Hi Ha Dao,
You can use the below translation rule and profile which will manipulate any type of calling number to International. If you want to be national, you can change the rule accordingly.
The profile has to be associated with either on the incoming or outgoing dial-plan based on your traffic.
voice translation-rule 120
rule 1 // // type any international
voice translation-profile manipulation
translate calling 120
Give it a Try.
