In step 2, calls that do not have an associated ANI are routed to an operator. In step 3, calls are routed from a phone to a specified extension. In step 4, operator or attendant local calls are routed, which are calls with less than seven digits, to a different vector. In steps 5 and 6, calls are routed from area codes, that is, Numbering Plan Areas (NPAs) 212 and 202 to a different vector. Calls that are not rerouted by the previous vector steps are put in a queue.
