MeetPointFinder!(Additional Charge)
This uses the National Exchange Carrier Association (NECA) Billing Percent data. This is also referred to a Meet Point percentage.  The route is calculated and then the percentage split is listed for each carrier involved in this circuit.
Find Alternate Routes:
Not all carriers have meet point arrangements between specific points.  C.O. Finder! will find all alternative routes using different carriers.  All of the alternate routes are listed in order of route mileage (shortest route first).  In this example, a total of 3 circuits are required to complete the path.  An interoffice circuit is required on both ends to connect to the meet point.
Route is displayed on map
The selected route is displayed on a map.
