Abstract
A system and method to expedite special number calls from a remote terminal that employs call control system comprising a control module and a translations database and is connected to the trunk group between the remote terminal and the local switching office. The translations database maintains translations for its associated remote terminal special number calls, including, but not limited to, 9-1-1 calls. When the call control system recognizes a special number call, it performs a look up in its translation database using the line ID as a key and substitutes a destination number for the special number and a calling line telephone number for the line ID. The call control system forwards the call to the local switching office, which treats the call as a trunk-to-trunk call. Advantageously, one (or more) trunk of the trunk group may be reserved solely for special number calls.
