CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
■ 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.
[EnableDetectRemoteMACChange] Determines whether the device changes the RTP
packets according to the MAC address of received
RTP packets and according to Gratuitous Address
Resolution Protocol (GARP) messages.
■ [0] = Nothing is changed.
■ [1] = If the device receives RTP packets with a
different source MAC address (than the MAC
address of the transmitted RTP packets), then it
sends RTP packets to this MAC address and
removes this IP entry from the device's ARP
cache table.
■ [2] = (Default) The device uses the received
GARP packets to change the MAC address of the
transmitted RTP packets.
■ [3] = Options 1 and 2 are used.
Note:
■ For the parameter to take effect, a device reset is
required.
