Version 7.2 1103 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
[DJBufOptFactor]
the parameter and for configuring the functionality, see
Configuring IP Profiles on page 423 or Configuring Tel Profiles
on page 459.
Note: If the functionality is configured for a specific profile, the
settings of the global parameter is ignored for calls associated
with the profile.
Analog Signal Transport Type
[AnalogSignalTransportType]
Determines the analog signal transport type.
 [0] Ignore Analog Signals = (Default) Ignore.
 [1] RFC 2833 Analog Signal Relay = Transfer hookflash
using RFC 2833.
Note: The parameter is applicable only to FXS and FXO
interfaces.
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
functionality per specific calls, using IP Profiles
(IpProfile_RTPRedundancyDepth). For a detailed description
of the parameter and for configuring this functionality in the IP
Profiles table, see ''Configuring IP Profiles'' on page 423.
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.
Enable RTP Redundancy
Negotiation
configure voip > sip-definition
settings > rtp-rdcy-nego-enbl
[EnableRTPRedundancyNegotiation]
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.
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.
