Description

ec_enabled

DWORD

1

Boolean

Enables echo cancellation capability on the input signal. Set to 1 to enable EC and 0 to disable it.

ec_gain

INT32

0

dB

Amount of amplification applied to echo input. Valid automatic gain range is -54 - +24.

ec_predelay

DWORD

0

ms

Output sample delay. Valid automatic gain range is 0 - 9.

input_agc_enable

DWORD

1

Boolean

Enables automatic gain control on the input signal. Set to 1 to enable AGC and 0 to disable it.

input_agc_targetampl

INT32

-19

dBm

Target amplitude for AGC. Valid range is -45 - 0.

input_agc_silenceampl

INT32

-40

dBm

Noise threshold for AGC. Gain adjustment is suspended for signals below this level. Valid range is -45 - 0.

input_gain

INT32

0

dB

Gain applied to the signal before it is encoded. If AGC is enabled, this is the initial gain. Valid automatic gain range is -12 - +12.

input_law

DWORD

0

Integer

G.711 law to be applied in the member's input. Valid values are:

0 = Default

1 = A-law

2 = mu-law

output_agc_enable

DWORD

1

Boolean

Enables automatic gain control on the output signal. Set to 1 to enable AGC and 0 to disable.

output_agc_targetampl

INT32

-19

dBm

Target amplitude for output AGC. Valid range is -45 - 0.

output_agc_silenceampl

INT32

-40

dBm

Noise threshold for output AGC. Gain adjustment is suspended for signals below this level. Valid range is -45 - 0.

output_gain

INT32

0

dB

Gain applied to the encoded audio. If output AGC is enabled, this is the initial gain. Valid automatic gain range is -12 - +12.

output_law

DWORD

0

Integer

G.711 law to be applied in the member's output. Valid values are:

0 = Default

1 = A-law

2 = mu-law

self_echo_enable

DWORD

0

Boolean

Indicates if the voice received from this member on its input is mixed and returned to that member on its output. This attribute can be enabled when the output is not connected to the member, but is actually used for recording. Set to 1 to enable and 0 to disable.

talker_enable

DWORD

0

Boolean

Enables the member as talker. Set to 1 to enable and 0 to disable.

listener_enable

DWORD

1

Boolean

Enables the member as listener. Set to 1 to enable and 0 to disable.

talker_privilege

DWORD

0

Boolean

Enables the member as privileged talker. Set to 1 to enable and 0 to disable.

dtmf_clamping_enable

DWORD

1

Boolean

Enables the DTMF clamping capability. Set to 1 to enable and 0 to disable.

dtmf_clamping_delay_line

DWORD

28

ms

Delay line to buffer the signal received by each member before removing the DTMF with the DTMF clamping module. Valid range is 0 - 28 ms.

tone_clamping_enable

DWORD

1

Boolean

Enables the tone clamping capability. Set to 1 to enable and 0 to disable.
