User's Manual 43. Configuration Parameters Reference
Parameter Description
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:
 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.
Web: RFC 2198 Payload Type
EMS: Redundancy Payload Type
[RFC2198PayloadType]
Defines the RTP redundancy packet payload type according
to RFC 2198.
The range is 96 to 127. The default is 104.
Note: This parameter is applicable only if the parameter
RTPRedundancyDepth is set to 1.
Web: Packing Factor
EMS: Packetization Factor
[RTPPackingFactor]
N/A. Controlled internally by the device according to the
selected coder.
Web/EMS: Basic RTP Packet Interval
[BasicRTPPacketInterval]
N/A. Controlled internally by the device according to the
selected coder.
Web: RTP Directional Control
[RTPDirectionControl]
N/A. Controlled internally by the device according to the
selected coder.
Web/EMS: RFC 2833 TX Payload
Type
[RFC2833TxPayloadType]
Defines the Tx RFC 2833 DTMF relay dynamic payload
type.
The valid range is 96 to 99, and 106 to 127. The default is
96. The 100, 102 to 105 range is allocated for proprietary
usage.
Notes:
 Certain vendors (e.g., Cisco) use payload type 101 for
RFC 2833.
 When RFC 2833 payload type negotiation is used (i.e.,
the parameter TxDTMFOption 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.
Web/EMS: RFC 2833 RX Payload
Type
[RFC2833RxPayloadType]
Defines the Rx RFC 2833 DTMF relay dynamic payload
type.
The valid range is 96 to 99, and 106 to 127. The default is
96. The 100, 102 to 105 range is allocated for proprietary
usage.
Notes:
 Certain vendors (e.g., Cisco) use payload type 101 for
RFC 2833.
 When RFC 2833 payload type negotiation is used (i.e.,
the parameter TxDTMFOption is set to 4), this payload
type is used for the received DTMF packets. If
