Remarks

WaitForSilence detects a specified period of silence on the call. This method can be useful if the application makes outgoing calls and needs to wait until the end of answering machine greetings before playing a message.

Please note that the telephony hardware must support hardware silence detection for this method to work. Regular voice modems do not support silence detection.
