What is cdx6500VoiceCfgDialToneLowerFrequencyAmplitude?

The amplitude, in 0.5 dB steps from -30 dBm to -3 dBm, of the lower dial-tone frequency component (-30 dBm turns that tone off). An admin adjusts this to make dial tone loudness match local telephony standards or to silence one of the two tone components.
