transmitted to the decoder (otherwise, if DTX is in use the frame does not need to be transmitted). If
the VAD flag is set the packet contains voice data (otherwise the frame is a silence frame). If the
Tone Frame flag is set the packet contains tone data. The amplitude and index of the tone are set in
the tone[] parameter of the Channel packet.
Channel Packet Bytes 20, 21, 22, 23 (tone.idx & tone.amp)
Appropriate values for tone.idx and tone.amp, are listed in Table 19 tone.idx—Channel-Parameter.
When tone signaling is inactive tone.idx should be set to NO TONE and tone.amp should be set to
zero.
