Zoom X6v VoIP manual Call Progress Tone Parameters

A negative dBm level can be offset by ipbx_tone_gain. Allowed values for freq are from 0 to 3000Hz. Allowed values for db levels are from –1 to –40 dB.

tone_on_timeX and tone_off_timeX are interleaved Tone On and Tone Off durations in msec. A value of zero for a Tone On time indicates a continuous tone. A value of zero for a Tone Off time produces silence, while a negative value (-1) terminates the tone pattern, removing the silencing. (With silencing, the voice channel is blocked until the tone pattern is stopped.) The maximum number of tones is four. The maximum number of on-to-off and off-to-on times counted individually is nine.

For example, the default setting for initial North American dial tone is:

{2, 0, 0, {350, -19, 440, -19}, {0}}

where:

2 is the number of frequency/dB pairs (350, -19,and 440, -19)

The first 0 is the number of on/off transitions in the tone pattern, in this case a constant tone. The second 0 indicates that the tone will be played until otherwise instructed.

The first pair of frequency/dB (350, -19) specifies that the first tone is at 350Hz with a level of -19dB.

The second pair of frequency/dB (440, -19) specifies that the second tone is at 440Hz with a level of -19dB.

The final {0} specifies that there are no on/off times and that the tone is constant.
