Parameter Description
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.
Web: Enable RTP Redundancy
Negotiation
[EnableRTPRedundancyNegotiation]
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.
