SIP User's Manual
Table 13-36: RTP/RTCP and T.38 Parameters
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 268.
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 268.
Determines the analog signal transport type.

[0] Ignore Analog Signals = Ignore (default).

[1] RFC 2833 Analog Signal Relay = Transfer hookflash
using RFC 2833.
Determines whether the device generates redundant
packets. This can be used for packet loss where the missing
information (audio) can be reconstructed at the receiver end
from the redundant data that arrives in the subsequent
packet(s).

[0] 0 = Disable the generation of redundant packets
(default).

[1] 1 = Enable the generation of RFC 2198 redundancy
packets (payload type defined by the parameter
RFC2198PayloadType).
Notes:

The RTP redundancy dynamic payload type can be
included in the SDP, by using the parameter
EnableRTPRedundancyNegotiation.

This parameter can also be configured per IP Profile,
using the IPProfile parameter.
Determines whether the device includes 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
