Sample name: ToneController-SendTones

Sample location: %ProgramFiles%\Microsoft Office Communications Server 2007 R2\UCMA SDK 2.0\UCMACore\Sample Applications\Collaboration\QuickStarts\AudioVideoCall\ ToneController-SendTones


The application establishes a connection to the designated target, after initializing platform and endpoints. After the call is connected, the application waits for the AudioVideoFlowto become active (the value of its Stateproperty changes to Active), it attaches a ToneController, and then sends a tone. After the tone is sent, the platform is shut down normally.


  • Basic audio/video call placement

  • Platform and endpoint initialization
