Dial String: Lets you enter the numbers that you want to convert into DTMF tones. The characters that you can use for DTMF are 0123456789ABCD*#,) and for MF 0123456789ABC*#,.
DTMF: DTMF is the most commonly used standard. DTMF strings are limited to 16 characters.

Leading Silence: Determines the length of the silent region before the first tone.

High Frequencies Gain: The DTMF signal consists of a mix between two tones. One high frequency tone and one low frequency tone. You can either choose to let the two tones have the same amplitude by leaving this at zero, or you can raise the high frequency tone by up to 12 dB. On some telephone lines, the high frequency tones are set 2 dB higher than the low ones.
Fade In/Fade Out Tones: If this option is activated, the generated tones will fade in and out.
