The phone number you call in the network is an alias for a group of numbers. Indeed, the translation of a toll-free number will vary with where you are. In a PBX, etc., this is called a rotary or hunt group. Originally, when you ordered 555-1000 and 30 lines, you'd actually get 555-1000 through 555-1029. More modern switching systems don't need to do that; they can associate 30 accesses with one number. A true PBX extension is something else--it has local significance only at the PBX, and is not known to the telephone network. There are "extensions" that really are associated with telephone numbers and either can be reached from the operator or by Direct Inward Dialing (that is the proper term).
