Abstract:
In an embodiment, call routing from a customer to a destination is provided by intercepting a call setup message sent from a customer switch intended to signal a switch to perform a call routing function. In response to the call setup message being intercepted, a routing engine is queried with the destination of the call for a specific route over which to carry the call to the destination. The call setup message is modified to include the specific route. The switch is directed with the modified call setup message to use the specific route to carry the call from the customer to the destination.
