Mediant 500L MSBR
Parameter Description
Web: Enable RTP Redundancy
Negotiation
CLI: rtp-rdcy-nego-enbl
[EnableRTPRedundancyNegotiation]
Enables the device to include 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.
Web: RFC 2198 Payload Type
EMS: Redundancy Payload Type
CLI: RTP-redundancy-payload-type
[RFC2198PayloadType]
Defines the 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.
Web: Packing Factor
EMS: Packetization Factor
[RTPPackingFactor]
N/A. Controlled internally by the device according to the
selected coder.
Web/EMS: Basic RTP Packet
Interval
[BasicRTPPacketInterval]
N/A. Controlled internally by the device according to the
selected coder.
Web: RTP Directional Control
[RTPDirectionControl]
N/A. Controlled internally by the device according to the
selected coder.
Web/EMS: RFC 2833 TX Payload
Type
CLI: telephony-events-payload-type-
tx
[RFC2833TxPayloadType]
Defines the Tx RFC 2833 DTMF relay dynamic payload type
for outbound calls.
The valid range is 96 to 127. The default is 96.
Note: When RFC 2833 payload type negotiation is used (i.e.,
the parameter TxDTMFOption is set to 4), this payload type is
used for the received DTMF packets. If negotiation isn't used,
this payload type is used for receive and for transmit.
Web/EMS: RFC 2833 RX Payload
Type
CLI: telephony-events-payload-type-
rx
[RFC2833RxPayloadType]
Defines the Rx RFC 2833 DTMF relay dynamic payload type
for inbound calls.
The valid range is 96 to 127. The default is 96.
Note: When RFC 2833 payload type negotiation is used (i.e.,
the parameter TxDTMFOption is set to 4), this payload type is
used for the received DTMF packets. If negotiation isn't used,
this payload type is used for receive and for transmit.
