RejectIncomingCalls (Managed Code Sample)

  • Artykuł

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

The RejectIncomingCalls sample illustrates how to reject incoming calls based on Automatic Number Information (ANI) service data. The sample uses a list of forbidden phone numbers. If the forbidden list contains the call's ANI, the application does not answer the call. The application also does not answer calls when no ANI is available. If the ANI is valid and not in the rejection list, the call is answered and the caller's ANI is played.

  • Rejecting incoming calls based on ANI
  • Using an IfElseActivity to determine whether a call should be rejected
  • Using a CallInfo to obtain the ANI
  • Playing telephone numbers using text-to-speech
  • Using AppendTextWithHint in a prompt to play the telephone number appropriately
  • Retrieving data from an XML data file
  • Logging an informational message using LoggingManager

Running the Sample

To run the sample

  1. In the Samples\Workflow\RejectIncomingCalls\ directory of the Speech Server installation directory, open the sample solution file.

    The application says the called phone number and says that the call has been accepted.

  6. Add phone numbers to the ForbiddenNumbers.xml file, and then verify that the calls are not accepted for these numbers.

  7. Use logging tools to view the message logged when a call is rejected.
