Class GeneratorImpl

java.lang.Object
  org.mobicents.media.server.impl.BaseComponent
      org.mobicents.media.server.impl.AbstractSource
          org.mobicents.media.server.impl.resource.dtmf.GeneratorImpl

All Implemented Interfaces:

Serializable, Component, MediaSource, DtmfGenerator

public class GeneratorImpl
extends AbstractSource
implements DtmfGenerator

InbandGenerator generates Inband DTMF Tone only for uncompressed LINEAR codec. After creating instance of InbandGenerator, it needs to be initialized so that all the Tones are generated and kept ready for transmission once start is called. By default the Tone duration is 80ms. This is suited for Tone Detector who has Tone duration of greater than 40 and less than 80ms. For Tone Detector who's Tone duration is set greater than 80ms may fail to detect Tone generated by InbandGenerator(with duration 80ms). In that case increase the duration here too.
