In looking at your dialplan it looks like you are just looking for 4 digits in the dial plan. You could change the table to accomodate more digits in the last table it says:

PreTranslator Create 1 4Digit DDI 3Digit Internal
/ PreTransId Entry Digits
/ ---------- ----- ------
PreTranslatorEntry Create 1 1 1
PreTranslatorEntry Create 1 2 2
PreTranslatorEntry Create 1 3 3


You could change these so that it spells out the DID numbers to accomodate the carrier. You could change as follows:

PreTranslator Create 1 7Digit DDI 3Digit Internal
/ PreTransId Entry Digits
/ ---------- ----- ------
PreTranslatorEntry Create 1 1 xxx2251
PreTranslatorEntry Create 1 2 xxxxxxx
PreTranslatorEntry Create 1 3 3


listing out each of the DID numbers. You then would also have to define where they go to as follows:

/ PreTransId Entry OperId Operation Value
/ ---------- ----- ------ --------- -----
PreTranslatorOperation Create 1 1 410
PreTranslatorOperation Create 1 2 (extension to direct call at)


Just make sure that you keep the numbers in the first table 1, 2, 3, 4, 5 etc so that they match the pretranslator ID so 1 to 1 and 2 to 2 etc.
