Cseries :: Can C3 Add A Standard Prefix To Each Number Dialed

We have a number of company Series 40 Nokia phones, such as thje C3, which we'd like to integrate with our company's PBX. We'd like to define a standard prefix (say 1111) which would be added to the beginning of each number dialed (be it from Contacts or a manually entered number). E.g. I choose to call "Mark" from my Contacts on the C3 whose stored cell number is 6944333333; the actual number that will be called will be 11116944333333.
