Version 7.2 1085 Mediant 500 MSBR
User's Manual 74. Configuration Parameters Reference
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.
[EnableDetectRemoteMACCha
nge] 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.

If the device is located in a network subnet which is connected
to other gateways using a router that uses Virtual Router
Redundancy Protocol (VRRP) for redundancy, then set the
parameter to 0 or 2.
RTP Base UDP Port Global parameter that defines the lower boundary of the UDP port
