Parameter Description
> silk-tx-inband-fec
[SilkTxInbandFEC]

[1] Enable
Silk Max Average Bit Rate
configure voip > media settings
> silk-max-average-bitrate
[SilkMaxAverageBitRate]
Defines the maximum average bit rate for the SILK coder.
The valid value range is 6,000 to 50,000. The default is 50,000.
The SILK coder is Skype's default audio codec used for Skype-to-
Skype calls.
Opus Max Average Bitrate
configure voip > sip-definition
settings > opus-max-avg-
bitrate
[OpusMaxAverageBitRate]
Defines the maximum average bit rate (in bps) for the Opus coder.
The valid value range is 6000 to 50,000. The default is 50,000.
configure voip > media settings
> vbr-coder-header-format
[VBRCoderHeaderFormat]
Determines the format of the RTP header for VBR coders.
 [0] = (Default) Payload only (no header, TOC, or m-factor) -
similar to RFC 3558 Header Free format.
 [1] = Supports RFC 2658 -
1 byte for interleaving header (always
0), TOC, no m-factor.
 [2] = Payload including TOC only, allow m-factor.
 [3] = RFC 3558 Interleave/Bundled format.
configure voip > media settings
> vbr-coder-hangover
[VBRCoderHangover]
Defines the required number of silence frames at the beginning of
each silence period when using the VBR coder silence
suppression.
The range is 0 to 255. The default is 1.
AMR Payload Format
[AmrOctetAlignedEnable]
Defines the AMR payload format type.
 [0] Bandwidth Efficient
 [1] Octet Aligned (default)
Note:
 The AMR payload type can also be configured per Coder Group
(see Configuring Coder Groups on page 427). The Coder Group
configuration overrides the parameter.
configure voip > media settings
> amr-header-format
[AMRCoderHeaderFormat]
Determines the payload format of the AMR header.
 [0] = Non-standard multiple frames packing in a single RTP
frame. Each frame has a CMR and TOC header.
 [1] = AMR frame according to RFC 3267 bundling.
 [2] = AMR frame according to RFC 3267 interleaving.
 [3] = AMR is passed using the AMR IF2 format.
Note:
 Bandwidth Efficient mode is not supported; the mode is always
Octet-aligned.
