Voice Volume is used to specify the input voice volume, output voice volume and
DTMF tone volume. The acceptable value for volume is an integer no less than
10 and no greater than 40.
The Dial Tone is sent to a customer or operator to indicate that the receiving end
is ready to receive dial pulses or DTMF signals. It is used in all types of dial
offices when the customer’s or operator’s dials produce dial pulses.
A Ring Back tone (or ringing tone) is an audible indication that is heard on the
telephone line by the caller while the phone they are calling is being rung. It is
normally a repeated tone, designed to assure the calling party that the called
party's line is ringing.
The Busy Tone indicates that the called customer’s line has been reached but
that it is busy, being wrong, or on permanent signal. When an operator applies a
busy signal, it is sometimes called a busy-back tone. Line Busy Tone is a Low
Tone that is on and off every 0.5 second.
The settings of Dial Tone, Ring Back Tone and Busy Tone depend on area. The
default settings for Asia are shown in the screenshot above for reference.
