CHAPTER60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
'RTP Redundancy Depth'
configure voip > media
rtp-rtcp > RTP-redundancy-
depth
[RTPRedundancyDepth]
Global parameter that enables the device to generate
RFC 2198 redundant packets. You can also configure
this feature per specific calls, using IP Profiles
(IpProfile_RTPRedundancyDepth). For a detailed
description of the parameter and for configuring this
feature in the IP Profiles table, see Configuring IP
Profiles.
Note: If this feature is configured for a specific IP
Profile, the settings of this global parameter is ignored
for calls associated with the IP Profile.
'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.
