44.10.4 RTP, RTCP and T.38 Parameters
The RTP, RTCP and T.38 parameters are described in the table below.
Table 44-37: 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 in an IP Profile
and/or a Tel Profile.

For more information on Jitter Buffer, see Dynamic Jitter
Buffer Operation on page
179 .
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 in an IP Profile
and/or a Tel Profile.


Buffer Operation on page

Web/EMS: Analog Signal Transport
Type
[AnalogSignalTransportType]
Determines the analog signal transport type.

[0] Ignore Analog Signals = (Default) Ignore.

[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 = (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.

The RTP redundancy dynamic payload type can be
included in the SDP, by using the
EnableRTPRedundancyNegotiation parameter.

This parameter can also be configured in an IP Profile.
