Defines the maximum delay and length (in msec) of the Jitter
Buffer.
The valid range is 150 to 2,000. The default is 250.
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:

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.
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 packets. This is
required, for example, in wireless networks where a high
percentage (up to 50%) of packet loss can be experienced.

[0] 0 = (Default) Disable.

[1] 1 = Enable - previous voice payload packet is added to
current packet.
Notes:

When enabled, you can configure the payload type, using the
RFC2198PayloadType parameter.

For the Gateway application only: The RTP redundancy
dynamic payload type can be included in the SDP, by using
the EnableRTPRedundancyNegotiation parameter.

The corresponding global parameter is
387
