The valid range is 0 to 12. The default factor is 10.
For more information on Jitter Buffer, see Configuring the Dynamic
Jitter Buffer on page 189.
Note:

For data (fax and modem) calls, set the parameter to 12.

The corresponding global parameter is DJBufOptFactor.
Enables the Silence Suppression feature. When enabled, the device,
upon detection of silence period during a call does not send packets,
thereby conserving bandwidth during the VoIP call.

[0] Disable (default)

[1] Enable = Silence Suppression is enabled.

[2] Enable Without Adaptation = A single silence packet is sent
during a silence period (applicable only to G.729).
Note:

If the coder is G.729, the value of the 'annexb' parameter of the
'a=fmtp' attribute in the SDP is determined by the following:

The parameter is set to Disable [0]: 'annexb=no'

The parameter is set to Enable [1]: 'annexb=yes'

The parameter is set to Enable Without Adaptation [2] and
IsCiscoSCEMode to [0]: 'annexb=yes'

Enable Without Adaptation is set to Enable Without
Adaptation [2] and IsCiscoSCEMode to [1]: 'annexb=no'

The corresponding global parameter is
EnableSilenceCompression.
Defines the maximum delay and length (in msec) of the Jitter Buffer.
The valid range is 150 to 2,000. The default is 250.
Enables the device's Echo Cancellation feature (i.e., echo from voice
calls is removed).

[0] Disable

[1] Line (default)
For a detailed description of the Echo Cancellation feature, see
Configuring Echo Cancellation on page 178.
Note: The corresponding global parameter is EnableEchoCanceller.
Defines the pulse-code modulation (PCM) input gain control (in
decibels). For the Gateway application: Defines the level of the
received signal for Tel-to-IP calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is InputGain.
Defines the voice gain control (in decibels). For the Gateway
application: Defines the level of the transmitted signal for IP-to-Tel
calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is VoiceVolume.
