Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
You can also configure the feature per specific calls,
using IP Profiles (IpProfile_JitterBufOptFactor) or Tel
Profiles (TelProfile_JitterBufOptFactor). For a
detailed description of the parameter and for
configuring the feature, see Configuring IP Profiles or
Configuring Tel Profiles.
Note: If the feature 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]
Defines 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 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.
'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).
