228 CHAPTER 3: DEVICE CONFIGURATION
If the DDI/DID numbers match your internal extension numbers, the
translator entries in your Dial Plan configuration file can be much simpler.
Example: You plan to use internal extensions from 100 through 299,
and the local telephone company assigns you numbers from
617-555-4100 through 617-555-4299. If the local telephone carrier
passes you three digits, you need no translator entries in the Dial Plan
configuration file. If the carrier passes you four digits, you could add a
single set of translator entries to the configuration file to remove the first
digit (4) and use the remaining three digits as the internal extension.
