You are here: CSP Developer’s Guide: Overview > 11 Call Routing > Introduction to Call Routing
You can configure the CSP to route calls without host intervention, and you can route calls interactively using the Route Control message. You use the Router Configuration Tool to create route tables that the CSP uses to route calls. Calls can be routed based upon the following:
• Incoming Channel
• Resource Group (Group of spans/channels)
• Digits (Called or Calling Party)
• Time of Day
