functionality in the IP Profile table, see ''Configuring IP Profiles'' on
page 391.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
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.
Notes:

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.
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.
N/A. Controlled internally by the device according to the selected
coder.
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.
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.
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.
