CallPilot uses dialing defaults to generate a DN that is understandable to the switch. You must define four dialing defaults to enable CallPilot features and custom applications calls outside your local switch:
CallPilot combines these prefixes to generate the required DN.
Example
A long distance call to the external telephone number 90115557890 includes the local prefix (9), the international prefix (011), and the local telephone number (5557890).
