A.11.4 RTP, RTCP and T.38 Parameters
The RTP, RTCP and T.38 parameters are described in the table below.
Table A-36: RTP/RTCP and T.38 Parameters
Parameter Description
Web: Dynamic Jitter Buffer
Minimum Delay
EMS: Minimal Delay (dB)
[DJBufMinDelay]
Defines the minimum delay (in msec) for the Dynamic Jitter
Buffer.
The valid range is 0 to 150. The default delay is 10.
Notes:
 This parameter can also be configured per IP Profile or Tel
Profile, using the IPProfile and TelProfile parameters
respectively.
 For more information on Jitter Buffer, see 'Dynamic Jitter
Buffer Operation' on page 153.
Web: Dynamic Jitter Buffer
Optimization Factor
EMS: Opt Factor
[DJBufOptFactor]
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.
 This parameter can also be configured per IP Profile or Tel
Profile, using the IPProfile and TelProfile parameters
respectively.
 For more information on Jitter Buffer, see 'Dynamic Jitter
Buffer Operation' on page 153.
Web/EMS: Analog Signal
Transport Type
[AnalogSignalTransportType]
Determines the analog signal transport type.
 [0] Ignore Analog Signals = Ignore (default).
 [1] RFC 2833 Analog Signal Relay = Transfer hookflash using
RFC 2833.
Web: RTP Redundancy Depth
EMS: Redundancy Depth
[RTPRedundancyDepth]
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 = Disable (default)
 [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.
 The RTP redundancy dynamic payload type can be included
in the SDP, by using the EnableRTPRedundancyNegotiation
parameter.
 This parameter can also be configured per
IP Profile, using the
IPProfile parameter.
Web: Enable RTP Redundancy
Negotiation
[EnableRTPRedundancyNegoti
ation]
Enables the device to included the RTP redundancy dynamic
payload type in the SDP, according to RFC 2198.
 [0] Disable (default)
 [1] Enable
When enabled, the device includes in the SDP message the RTP
payload type "RED" and the payload type configured by the
