Summary:                    [patch] 'Silence' is truncated in Record()
Description: 
When using Record with the silence detection feature, the stream is written
out to the given file. However, if only 'silence' is detected, this file is
then truncated to the first second of the recording (8016 bytes for alaw
e1).

This causes a problem for IVR applications, even if only silence is
detected it can still be of use in data collection as silence may not
really be all silence (e.g. someone talking quietly) or this data is
utilised for other verification reasons. Silence detection should not have
right to remove any recorded data, at the very least it should be a
configuration or argument option.

This can be tested via the sample AEL code:

context mycontext {

    80000000 => {
      Set(count=0);
    testing:
      Set(count=$[${count} +1]);
      //TESTING, silence 10 - max 13//
      Set(start=${EPOCH});
      Record(/tmp/silenceRecording${count}.alaw,10,13,u);
      Set(rlength=$[${EPOCH} - ${start} - 1]);
      NoOP(SILENCE IS: ${RECORD_STATUS});
      NoOP(RLENGTH IS: ${rlength});
      jump 80000000,testing at mycontext;
}
