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
by the parameter RFC2198PayloadType.
a=rtpmap:<PT> RED/8000
Where <PT> is the payload type as defined by
RFC2198PayloadType. The device sends the INVITE
message with "a=rtpmap:<PT> RED/8000" and responds
with a 18x/200 OK and "a=rtpmap:<PT> RED/8000" in the
SDP.
Notes:
For this feature to be functional, you must also set the
parameter RTPRedundancyDepth to 1 (i.e., enabled).
Currently, the negotiation of "RED" payload type is not
supported and therefore, it should be configured to the
same PT value for both parties.
RTP redundancy packet payload type according to RFC
2198.
The range is 96 to 127. The default is 104.
Note: This parameter is applicable only if the parameter
RTPRedundancyDepth is set to 1.
