Description

busycount

DWORD

4

count

Number of non-precise busy tones that must occur before busy or fast busy is reported. Valid range is 1 to 32767.

leakagetime

DWORD

8

ms

Do not modify.

maxbusy

DWORD

1500

ms

Threshold time defining the total time period (on time plus off time) for distinguishing between slow busy and ringing tone. Valid range is 0 to 32767.

maxreorder

DWORD

700

ms

Threshold time defining the total time period (on time plus off time) for distinguishing between fast busy (reorder) and slow busy. Valid range is 0 to 32767.

maxring

DWORD

3000

ms

Maximum duration of a tone to distinguish a ringing tone from a dial tone. Valid range is 0 to 32767.

maxringperiod

DWORD

8000

ms

Length of time of the last ringing tone plus the silence that follows, before call progress reports a ringing-ended event. Valid range is 0 to 32767.

noiselevel

DWORD

0x14000

IDU

Do not modify.

precmask

DWORD

7

mask

Mask to control which precise detectors to run. A value can be formed by using the OR operator with any of the following bit masks:

  • NCC_CPMSK_PRECISE_425 (0x0008) 425 Hz tone (busy and reorder tone, non-US)

  • NCC_CPMSK_PRECISE_BUSY (0x0004): Busy and reorder tone (US)

  • NCC_CPMSK_PRECISE_CED (0x0001): CED tone modem

  • NCC_CPMSK_PRECISE_NU (0x0040): Unassigned number

  • NCC_CPMSK_PRECISE_SIT (0x0002): SIT

  • NCC_CPMSK_PRECISE_SITEXT (0x0010): SIT type reporting

  • NCC_CPMSK_PRECISE_TDD (0x0020): TDD/TTY device

 

Only three of the four detectors can run concurrently. If all four detectors are specified, busy and reorder tones are determined by cadence alone, and only the SIT, CED, and TDD/TTY detectors are enabled.

Busy and reorder tone (bit value 0x0004) and the 425 Hz tone selection (bit value 0x0008) are mutually exclusive. If you choose both, only the 425 Hz filter takes effect.

precqualtime

DWORD

150

ms

Precise tone qualification time. All precise tones must be longer than this value to qualify. Valid range is 0 to 32767.

qualtonetime1

DWORD

60

ms

Do not modify.

qualtonetime2

DWORD

80

ms

Do not modify.

qualvoicetime1

DWORD

60

ms

Do not modify.

qualvoicetime2

DWORD

60

ms

Do not modify.

ringcount

DWORD

7

count

The number of ring tones that must occur before NO_ANSWER is reported. Valid range is 1 to 32767.

silencelevel

INT32

-40

dBm

Maximum signal level that is considered to be silence. Valid range is -46 to -34.

silencetime

DWORD

1500

ms

Minimum length of a silent period after voice is detected before call progress reports a voice-ended event.

stopmask

DWORD

0

mask

Mask to control which events cause call progress to stop. A value can be formed by using the OR operator with any of the following bit masks or by using one of the specified constants:

  • NCC_CPSTOP_ON_RINGTONE (0x0000): Ring tone

  • NCC_CPSTOP_ON_RINGQUIT (0x0002): Ring end

  • NCC_CPSTOP_ON_VOICE_BEGIN (0x0004): Ring end

  • NCC_CPSTOP_ON_VOICE_END (0x0040): Voice end

  • NCC_CPSTOP_ON_VOICE_EXT (0x0020): Extended voice duration

  • NCC_CPSTOP_ON_VOICE_LONG (0x0010): Long voice duration

  • NCC_CPSTOP_ON_VOICE_MEDIUM (0x0008): Medium voice duration

timeout

DWORD

10000

ms

Maximum time that can elapse with no stimulus from the network before call progress stops with reason of timeout. If the value is set to zero, the timer is disabled.

voicextended

DWORD

9000

ms

Minimum length of time voice must be detected before call progress reports an extended-voice event.

voicelong

DWORD

6000

ms

Minimum length of time voice must be detected before call progress reports a long-voice event.

voicemedium

DWORD

3000

ms

Minimum length of time voice must be detected before call progress reports a medium-voice event.

voicetoneratio

DWORD

0x30000

IDU

Do not modify.
