The coder parameters are described in the table below.
Table 65-35: Coder Parameters
Parameter Description
configure voip > media settings
> EVRC-VAD-enable
[EnableEVRCVAD]
Enables the EVRC voice activity detector.
 [0] = Disable (default)
 [1] = Enable
Note: The parameter is applicable only to the EVRC coder.
configure voip > media settings
> EVRC-dtx-min
[EVRCDTXMin]
Defines the minimum gap between two SID frames when using the
EVRC voice activity detector. Units are in EVRC frame size (20
msec).
The range is 0 to 20000. The default is 12.
Note: The parameter is applicable only to the EVRC coder.
configure voip > media settings
> EVRC-dtx-max
[EVRCDTXMax]
Defines the maximum gap between two SID frames when using the
EVRC voice activity detector. Units are in EVRC frame size (20
msec).
The range is 0 to 20000. The default is 32.
Note: The parameter is applicable only to the EVRC coder.
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.
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.
