6. Configuration Parameters Reference
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.
N/A. Controlled internally by the device according to the
selected coder.

instead.
Lower boundary of UDP port used for RTP, RTCP (RTP
port + 1) and T.38 (RTP port + 2). The upper boundary is
the Base UDP Port + 10 * (number of device's channels).
The range of possible UDP ports is 6,000 to 64,000. The
default base UDP port is 6000.
For example: If the Base UDP Port is set to 6000 (default)
then:
1) The first channel uses the following ports RTP 6000,
RTCP 6001, and T.38 6002, 2) the second channel uses
RTP 6010, RTCP 6011, and T.38 6012, etc.
Notes:

If RTP Base UDP Port is not a factor of 10, the following
message is generated: 'invalid local RTP port'.

For detailed information on the default RTP/RTCP/T.38
port allocation, refer to the Product Reference Manual

For this parameter to take effect, a device reset is
required.
