Mediant 500 MSBR
Parameter Description
SIP entity does not support RTP redundancy.
Note:

To enable the device to generate RFC 2198 redundant
packets, use the IPProfile_RTPRedundancyDepth parameter.

To configure the payload type in the SDP offer for RTP
redundancy, use the RFC2198PayloadType.
RTCP Mode
sbc-rtcp-mode
[IPProfile_SBCRTCPMode]
Defines how the device handles RTCP packets during call
sessions for the SIP entity associated with the IP Profile. This is
useful for interworking RTCP between SIP entities. For example,
this may be necessary when incoming RTCP is not compatible
with the destination SIP entity's (this IP Profile) RTCP support. In
such a scenario, the device can generate the RTCP and send it
to the SIP entity.

[0] Transparent = (Default) RTCP is forwarded as is.

[1] Generate Always = Generates RTCP packets during
active and inactive (e.g., during call hold) RTP periods (i.e.,
media is 'a=recvonly' or 'a=inactive' in the INVITE SDP).

[2] Generate only if RTP Active = Generates RTCP packets
only during active RTP periods. In other words, the device
does not generate RTCP when there is no RTP traffic (such
as when a call is on hold).
Note: The corresponding global parameter is SBCRTCPMode.
Jitter Compensation
sbc-jitter-compensation
[IpProfile_SBCJitterCompensatio
n]
Enables the on-demand jitter buffer for SBC calls. The jitter
buffer is useful when incoming packets are received at
inconsistent intervals (i.e., packet delay variation). The jitter
buffer stores the packets and sends them out at a constant rate
(according to the coder's settings).

[0] Disable (default)

[1] Enable
Note:

The jitter buffer parameters, 'Dynamic Jitter Buffer Minimum
Delay' (DJBufMinDelay) and 'Dynamic Jitter Buffer
Optimization Factor' (DJBufOptFactor) can be used to
configure minimum packet delay only when transcoding is
employed.
ICE Mode
ice-mode
[IPProfile_SBCIceMode]
Enables Interactive Connectivity Establishment (ICE) Lite for the
SIP entity associated with the IP Profile. ICE is a methodology
for NAT traversal, employing the Session Traversal Utilities for
NAT (STUN) and Traversal Using Relays around NAT (TURN)
protocols to provide a peer with a public IP address and port that
can be used to connect to a remote peer.

[0] Disable (default)

[1] Lite
For more information on ICE Lite, see ICE Lite.
Note: As ICE has been defined by the WebRTC standard as
mandatory, the support is important for deployments
implementing WebRTC. For more information on WebRTC, see
WebRTC.
SDP Handle RTCP
sbc-sdp-handle-rtcp
Enables the interworking of the RTCP attribute, 'a=rtcp' (RTCP)
in the SDP, for the SIP entity associated with the IP Profile. The
RTCP attribute is used to indicate the RTCP port for media when
