Specify Tone Parameters for Global Tone Detection
$global_tone line toneid parmlist
The syntax for this command depends on whether the line hardware is Dialogic or Dialogic Diva. For the latter, a $global_tone_parms command is also required.
This command specifies a tone which is recognized during CopiaFacts operations and can be used for application purposes, for example for detecting a specific answering machine type. To determine the parameters to enter, it is easiest to prepare a recording of the tone in a VOX or WAV file use a utility such as Adobe Audition (formerly CoolEdit 2000) to analyse the frequencies.
The parameters on this command are used as follows:
| line | the line number or line group(s) affected, or * for all lines. Up to 32 tones may be defined for each line. |
| toneid | The tone ID number to identify the tone (a value 1 to 32). Note that each Dialogic board can support a different number of tones per channel. For some older boards, this number is substantially less than 32. For Dialogic Diva boards, CopiaFacts will analyse up to 32 separate tones. |
| parmlist | a list of nine (Dialogic) or two (Dialogic Diva) white-space-separated values as follows: |
| freq1 | the first or only tone frequency in Hz. |
| fq1dev | the deviation of the above tone in Hz. This is curently the last of the parameters used for Dialogic Diva boards. |
| freq2 | the second tone frequency in Hz of a dual tone (or zero for a single tone) |
| fq2dev | the deviation of the above tone in Hz (or zero for a single tone) |
| ontime | the cadence on-time in 10ms units. If the tone is continuous, enter here half the minimum time value. |
| ontdev | the cadence on-time deviation in 10ms units. If the tone is continuous, enter here minus half the minimum time value. |
| offtime | the cadence off-time in 10ms units. If the tone is continuous, enter zero. |
| offtdev | the cadence off-time deviation in 10ms units. If the tone is continuous, enter zero. |
| repcnt | the cadence minimum repetition count. If the tone is continuous, enter zero. |
To enable tone detection, assign values to the GTD_CHECK system variable. When a tone is detected, the tone ID is returned in the GTD_TONEID variable.
Hardware Issues: Dialogic and Dialogic Diva only
Example:
Specify a continuous single tone of 375Hz with a minimum time of .2 seconds (Dialogic):
$global_tone * 1 375 20 0 0 10 -10 0 0 0
Specify a single tone of between 372Hz and 378Hz (Dialogic Diva):
$global_tone * 1 375 3
