User's Manual
Defines the minimum delay (in msec) of the device's
dynamic Jitter Buffer.
The valid range is 0 to 150. The default delay is 10.
Notes:

For more information on the Jitter Buffer, see Dynamic
Jitter Buffer Operation on page 172.

The corresponding global parameter is DJBufMinDelay.
Defines the Dynamic Jitter Buffer frame error/delay
optimization factor.
The valid range is 0 to 12. The default factor is 10.
Notes:

For data (fax and modem) calls, set this parameter to 12.

For more information on Jitter Buffer, see Dynamic Jitter
Buffer Operation on page 172.

The corresponding global parameter is DJBufOptFactor.
Defines the DiffServ value for Premium Media class of
service (CoS) content.
The valid range is 0 to 63. The default is 46.
Note: The corresponding global parameter is
PremiumServiceClassMediaDiffServ.
Defines the DiffServ value for Premium Control CoS content
(Call Control applications).
The valid range is 0 to 63. The default is 40.
Note: The corresponding global parameter is
PremiumServiceClassControlDiffServ.
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).
Notes:

If the coder is G.729, the value of the 'annexb' parameter
of the 'fmtp' attribute in the SDP is determined by the
following:

This parameter is set to Disable [0]: 'annexb=no'

This parameter is set to Enable [1]: 'annexb=yes'

This 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.
Enables the device to generate RFC 2198 redundant
packets. This can be used for packet loss where the missing
information (audio) can be reconstructed at the receiver's
end from the redundant data that arrives in subsequent
