Mediant 1000B Gateway & E-SBC
Parameter Description
Enable RTP Redundancy
Negotiation
configure voip > sip-definition
settings > 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 = 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.
Note:
 The parameter is applicable only to the Gateway
application.
 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.
RFC 2198 Payload Type
configure voip > media rtp-rtcp >
RTP-redundancy-payload-type
[RFC2198PayloadType]
Defines the RTP redundancy packet payload type (according
to RFC 2198).
The valid value is 96 to 127. The default is 104.
Note: The parameter is applicable only if the
RTPRedundancyDepth parameter is set to 1.
Packing Factor
[RTPPackingFactor]
N/A. Controlled internally by the device according to the
selected coder.
RFC 2833 TX Payload Type
configure voip > gateway dtmf-supp-
service dtmf-and-dialing >
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 FirstTxDTMFOption 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.
RFC 2833 RX Payload Type
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 FirstTxDTMFOption 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.
